Blender is acting up for me when like things are missing screen randomly goes blacks scripts apparently missing. I have reinstalled it many times and Its the same thing I don’t know whats going on.
do you have python installed?
yes I do have it installed.
It’s not your blender, it’s your operating system. You’re using Vista. You probably need to update your video drivers. Take a look at the thread, Solutions to common problems. The thread predates Vista (by a lot) so you’ll probably find something about working with Vista toward the end of the thread.
