Hey,

since some weeks i have a real curious bug in 3dsmax.
With less words: Everytime i want to open a File Dialog Window in 3dsmax it crashes directly after the mouse click without any warning. It is like something has killed my 3dsmax.exe process.
In other words: I can’t work anymore. Some examples for the File window are:
File --> Open
File --> Save as
MAXScript --> Run Script
and so on…

The only way i can save my MaxFile is to overwrite my existing File by pressing “CTRL+S”
Another curious thing is, that it seems to happen with random max files. If i work on a new scene everything is perfect, but after a week this problem happens with this scene too.
First i thought that this problem occurs only on my computer, but yesterday another worker of our company had the same issue on a max file, which i have never seen before.
Both of us haven’t installed any software the last weeks.
Another idea was, that we have a new windows hotfix, which occurs this issue, but all of our other machines are up to date too.

Here are my system specifications:
3Ds Max 2009 SP1 + VRay 1.5 SP5
Windows 7 Pro x64 Sp1,
Intel i7 920
12GB RAM
Nvidia QuadroFX 4800 (driver 275.36)

What the hell am i doing wrong?
Please help!!!
