Since I installed the V4 ProPack strange things are happening. If I save an incomplete V4 file and try to work on it later the following happens:

1. Hourglass is busy and finally the curser comes back. Screen is blank not even a frame. When I try to open a new file I am asked if the open file should be saved. The question is, where could this file be viewed, other then the screen in front of me?

2. If I have to use V4 I must complete the project without saving it. As long as the file is open everything functions great. Renders are perfect. But this is where it ends. Once saved it cannot be reopened.
   I deleted the Poser.ini and the .xml files. I set Render cache to 1 instead of 10. Nothing.

I have also noticed that saved V3 files open with difficulty. I never had this problem before. Also started with the addition of V4.

Does anybody else experience these blank screens? Any idea what might be the cause of it?
I have read through the other threads but nothing really fits my problem.

I am working with WIN2000 and not XP.
CPU 3GHZ Pentium 4
RAM 1GB
HD 250GB
Intel Extreme Graphic2 Controller on Motherboard. 3MG per minute.

Hope you can help me!
