when switching to the materail buttons, blender crashs my whole system (bluescreen). it seems to be a problem of my graphiccard and the new material-preview. i can only view & edit material settings when blender is windowed (no fullscreen).
bluescreen crashs only in bf-cvs and tuhopuu builds. long time ago i had problems with the opengl drawing, but no problems at the last time (which seems the be a issue of my gfx).
i don't know where the opengl tracker is to find so i post it here.

If you mean the rejected hackish code that adds a "Fullscreen" button in the top header of Blender? That is instable code, and will crash all over yes.
But in the current official 2.42 rc that option is not available.

no ton, i don't mean the fullscreen (option) INSIDE blender, i mean the window which is in fullscreen, when you start up blender (in normal case).

But when manually drag the window edges to fill the entire screen it doesn't crash?
It might help to check for settings in the ATI driver... like 16/24/23 bits, optimization options, etc.
The new preview in the buttons window uses float images to draw, which is a very basic opengl 1.0 option, but I've heard from other ATI windows users it doesn't work well. Just to be sure, I've now added code that converts these images to regular 32 bits before drawing.
If you can get a build with this change (or build yourself, or join irc.freenode.net #blendercoders) please check!

Manually drag: Sometimes it goes well, but in the most time it doesn't.
I've checked the options in the driver, but it seems there are almost none. I've tested 16bit and 32bit resolution, very time the same...crash. the build from jms (21.06.2006) was the same, but i didn't crash when is use the screen layout of him. When i use my own or the "standard" one, it will crash, when i switch to the material buttons.

It's becoming more and more mysterious...
- did you check for driver updates on ATI site?
- there must be a driver menu with opengl settings, also where you can use an 'accelleration' slider, set that to zero

I use the latest driver from ATI.
I did check the 'accelleration slider' and it works with 'without accelleration' and 'accelleration on level 1'. When i use these settings, blender is pain to me.

Wait for the official 2.42 RC2 testbuild for windows, it has a different drawing for preview renders, hopefully that will survive for you :)
