GUI Flicker / Refresh problem

Hello eveybody,

I’m relative new to blender so forgive me for my noob questions. I have a weird problem with the blender GUI. It flickers / refreshes allot. Especialy when i make use of the menu’s the GUI seems to disapeare and return really fast.

Sometimes i have to press a menu item twice to activate it.

I tried both stable and daily build. Both same problem.

Running on:

Blender 2.61
Dell Precision M4500 Laptop
Windows 7 / 32 Bit
NVIDEA Quadro FX 1800M (with latest drivers)
Intel i7 Core Q720


Same for me, it is really annoying.
