Photoshop crashes when apply mixer brush?

[zinomori]

For some reason Photoshop crashes on my desktop computer (Windows Vista) when I try to apply mixer brush on my photo. My Photoshop is updated to the latest. I also updated my graphic drivers, but had no success. Just wondering what else I need to check? Does anyone have the same problem? I really need your help to fix this problem.


Thanks in advance.

Which version of photoshop?

I guess CS5. I think the mixer brush is a new tool in it.

It is also interesting to know if Windows and Photoshop are 64 or 32 bits.
