Patch 436 and no Windows mode

Hi Folks

I have a problem.
Yesterday i bought the Game of the Year edition.
This edition comes with the 436 patch.
It is already installed with the normal game.
But if i run the Game no problems occur.
But if i want to minimize to a window or to tray UT crashes with a long error message.

in the Versiion 400 i Had befor
So the Problem seems to bee the patch.
Cause if i patched my 400 version to 436 the same problem appears.
if i delete the UT Folder completly and reinstall the 400 everything is fine again.

I also tried the ne D3D .dll for the nvidia card but this crashes stay.

Something abaut my system.

Has anybody an idea what this can be.
Cause its boring if you connect to an server and have to wait 5 minutes for a mutator and you can nothing do than wath the percents raising

Thats something i can test.
I Think its Different. But now iam at work and cant test it.
But if i think about it. mh
I'am playing UT in 32 bit both 400 and 436 its some of the first things i change after the resolution.
under 400 and under 436.

The only thing is that perhaps the 436 has problems with changing the rendering deep if i go in window mode. i'll try it when i'am @ home

if i set the rendering deep in windows same deep it works.
But why does it work in 400 different then in 436 ??

Any Idea ?
