Does this happen to anyone else?
Using 2.59 recent download
Things to try:
- Update your graphics card drivers. Don’t do an auto search for drivers actually go to the manufacturers site and download the latest
- If you use an NVidia card, disable anti-aliasing in the control panel
- Run blender as an administrator (note the same as being logged in as an administator so do a forum search as instructions have been given here many times)
if you can get to user preferences try different window draw modes,
