Are there any such known/reported issues? While trying to reproduce the CUDA checkbox missing bug on my PC, in several of my tries to close and run GPU-Z again, on trying to start the program I got about 3-4 freezes (GPU-Z splash screen appears and then shortly afterwards becomes gray), and Windows 7 informed me that GPU-Z has hanged. Only GPU-Z hanged, the OS itself and other apps were fine. Then after those several freezes and me having to tell Windows 7 to close the app, GPU-Z started running (starting without a freeze/lockup) fine again. Note: I do not have GPU-Z set to start with Windows 7, I start it manually after that. System specs: in my profile. GPU-Z version: latest (0.6.9) Possible culprits: Stardock Fences 2, Core Temp, Xfire Beta (version 2.36), Adobe Flash running in Chrome or some IM client (I believe ICQ and AIM use Flash).
