Logos 4 Windows on Parallels problem
I just bought a new computer and am experiencing very bad screen corruption issues with Logos 4 under Windows 7/ Parallels 5. I wonder if anyone here has experienced the same issues?
Logos loads and starts normally, but soon as I hover my mouse over various parts of the application the screen gets corrupted. They range from black rectangles to pixel corruption, sometimes recovering momentarily as some panels get redrawn. When it was really bad it became something like:
For those of you who have success running Logos 4 under Win 7/ Parallels, is there any settings that need to be changed either under the Parallels or Windows 7 to get the application working properly? I'm wondering whether Parallels, Windows 7, or the fact that it is a Chinese version of Windows 7, that is causing the problem.
Here's my configuration:
iMac 2.8G Intel i7/ 8GB/ OSX 10.6.2; Parallels Desktop 5 (build 5.0.9220); Windows 7 (Win Home Prem 7 32-bit Chin Trad Hong Kong OEM)
Would be most grateful for any help/ advices!

I turned off 3D in the Virtual Machine graphics card setting. I also turned off aero in Win 7 itself. That seems to help performance and some minor display issues I was having. Make sure you are giving it enough memory and CPU too. I have an 8 core and give Windows 4 and 1.5 Gigs of memory. That seems to be the happy medium on my machine.
How do you turn off aero in windows 7?
Right Click your desktop and choose "personalize desktop"
That will open a window giving you different background themes. At the top, you will Aero themes, toward the bottom you will see Classic and High contrast themes. Choose the windows 7 basic or XP classic. Turning off 3D in the VM Settings has been helpful for some people as well.
Here is a step by step. http://www.howtogeek.com/howto/windows-vista/disable-aero-on-windows-vista/
In Parallels 4 that was true but in 5 my understanding is that you can use as many as you want. That said it crashes a Vista VM at work if I use more than 1 (on a 4 core) but with Windows 7 4 cores seemed to be the snappiest. I have played with so many setting I may go back and try again. Turning of 3D and Aero is by far the biggest improvement though.
read in a post earlier that Paralells' staff says you shouldn't give any more than two cores to their VM--the machine runs slower on more than two cores and more than 2 GB of RAM

I have tried two Parallels 5 and XP configurations—2Gb and 4GB RAM. There is hardly any measurable difference in L4 searches. Most of the time it favors the 4GB configuration, but not by much. The overall speed of the application does not seem to be much different. I guess I would say, it does not matter very much.
Thanks for all your replies! I tried your suggestions but very unfortunately they didn't work on my computer. The Win 7 that was installed in the computer (by the store guy) was a version that didn't have Aero so I guess there's no need to disable it (the option is also absent), and on the Parallels side, the option to enable/disable 3D was somehow dimmed. [:'(]
I'll try get two copies of Windows (Win XP/ Win 7) first thing tomorrow and try to install them with Bootcamp. Hopefully I'll be able to get something which works that way.
I can't even get paralells to connect now. Strange needing an internet connection just to run windows 7 now. In hindsight, I don't get the whole 'mac' phenom anyway. So far the biggest waste of time and money ever. Better the devil you know(microsoft), though I'd rather not know any. I thought PC's were a pain. Least they work. Lotta money for a program I can't even use except as a really expensive reader (mac) I've gone all through these posts, at least the people seem cool.
Maybe God wants me to stick to paper. Not much progress there though. <><
wow, troubles with the Microsoft and Apple platforms. That is frustrating. Your posts remind me of my Mother In Law. Boy, if there is problem to find, she finds it. I am always dong tech support for her Windows, Office Software, AOL, her Palm, and her boradband service. Somehow she brings out the worst in technology, but she has me to help :-)
I have a suggestion for you. Do you live near an Apple Store? It sounds like you could benefit greatfly by setting up an appointment for some hands on support and training. You can do this very easily on-line at apple.com. Pick a day, time and location and then show up. It is very easy the times I have used it :-) The Apple Techs are most helpful and can get your Parallels working for you and also provide some valuable instructions.
Not sure about Parallels, but I get some rendering issues when I have 3d turned on in Fusion. Do you have 3d disabled on Parallels? Might give that a try and see if it helps.
Wow, thanks for all your responses. Now I'll have to wait till I get off work to try your suggestions when I go back home.
Actually I'm also wondering if I should setup Windows 7 to run with bootcamp. Has anyone been using Bootcamp with Windows 7, and are there any issues with Logos 4? Or should I wait for the Bootcamp update with official Win 7 support (they said before the end of this year but hey, isn't it already the end of the year today... [;)])?
Amy, I am running Windows 7 (64 bit) Bootcamp in 10.6.2. and while I am running Fusion, I did try it out with Parallels as well. Works like a champ, no problems at all.
