Always when I open call stack window, ollydbg crashes. How could I gather more info to help fix this?

Exactly when does it crash - as soon as you press Alt+K (or View menu | Call Stack)? -- ive never had any problems with Call Stack
What version of OllyDbg are you using? -- im using 1.08b
What OS are you using? -- im using Win2K
Does it crash on just some processes, or all?

Ollydbg hangs, when Call stack window appears on the screen. I use winxp and 1.08b. Callstack works fine with some processes.
