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!
