Ableton Forum

I solved it by uninstalling my intellimouse software and drivers - mouse works fine without them and problem gone!

Live ver. 7.0.1
My PC:
Dell Inspiron 6400, Intel Core 2 Duo, 2GHz, 2GB RAM, Ableton Live
7.0.1, Edirol UA-25, ATI Mobility Radeon X1400

Problem:
submenus and vst windows being sometimes distorted and disappears
