Not Responding
Hello, can anyone help, I use Logos 4 almost every day for Sermon Preparation. Yesterday and today it is very sluggish, with the message 'not responding' showing regularly and sometimes the whole program 'grays' out.
Almost every second scroll of a page results in the 'not responding' message, then the page jumps to catch up when it does respond.
I have version 4.2a SR-5 (4.21.5.0959)
Thanks - William Horsburgh

There's a current ongoing thread where people are discussing performance problems, which have been an issue all along for people with less than the top-end machines (though even I have the occasional "Not responding" even with a very fast machine. I don't know of any reason why it would suddenly have gotten slower than it was for you a couple of days ago, unless perhaps your Internet connection is compromised temporarily (your ISP having a bad day, or someone else in your household using the bandwidth to download a movie at the same time or something like that). Logos does do a lot of connecting to the Internet for the purposes of Sync. If you set "Use Internet = No" in Program Settings, and restart Logos, it should speed things up somewhat for the time being, but you will have to sync manually every so often (by typing "sync now" command in the command bar), to ensure your user data is backed up.
Here are some other suggestions for improving performance: http://wiki.logos.com/Logos_Running_Slowly
EDIT: BTW, are you on Mac or Windows? Here's another thread where someone reported scrolling has slowed down noticeably in the latest release on Mac: http://community.logos.com/forums/t/32522.aspx
Thanks Rosie,
Turning off the internet has transformed the program.
Your help is greatly appreciated.
I had also disconnected a number of links between books and bibles, now that I've begun to reconnect them the 'not responding' warning is back, but nowhere as debilitating as previously. Disconnecting the internet has made a significant change.
Now, when I move from one open panel to another there is a pregnant pause, and when I try to highlight and copy text it falters.
It would be a great help if it were possible to get the program to work smoothly and consistently.
My Laptop is only a year old, running windows 7 64 bit and has 3 gb of memory, so it has to be a glitch in the program which is causing these delays.
Thanks again
It's not really a single "glitch" in the program, I'm afraid. Logos is built on top of Microsoft's WPF (Windows Presentation Foundation) which is notoriously slow all around. The dependencies on that run deep, and it's not easy for them to improve the performance of it. They work on optimizations every so often, but there's only so much they can do. Only a major revamp of the software to ditch the underlying display engine and write their own would fix the problems for real, but that would take a huge amount of development time, and they'd be left with a whole new slew of technical challenges plus having to maintain that code too (a task which they now get to delegate to Microsoft; a dubious dependency for sure).
It all depends on your point of view. I believe building an item on a bad foundation is a "single glitch." If people who have a "super-fast computer" are having performance issues, then the solution for the issue does not lie with users buying faster computers as implied by Bob when he states that L4 was designed for the future. New computers will only mask the underlying problems.
Logos gambled when they took the risk to develop L4 on a promising but untested development platform. If you ask me, Logos lost on this gamble. Not only has WPF has not performed as promised, there are rumors of internal conflict at Microsoft over the future of WPF. There are issues with .NET3 that are solved with .NET4, but L4 cannot be moved to .NET4 because of there are other issues with .NET4 & L4.
To quote Kenny Rogers, "You've got to know when to hold 'em, Know when to fold 'em, Know when to walk away, Know when to run."
IMHO, it is time for Logos to fold on WPF and to run away from it. There is no reason to continue to throw away any more good money into this losing situation.
Complex visual filters and an excessive number links between panels are the biggest causes of Logos slow down in my experience. You might want to adjust your layout if you using either of these features.

I wonder if a future release will include code to reduce the Internet activity when the program is busy...
