I was getting some weirdness after I updated today and then came to the forums, looking to find out why I cannot delete someone's item from my land; I'm wondering, also, if he grabbed a script off an object of mine, nothing special at all, just a rotation.. (mind wandering....)
Anyway, if you're getting some real graphics issues, try going into >
PREFERENCES (CTRL-P) > GRAPHICS > HARDWARE OPTIONS (in lower right)
and unchecking the ENABLE VBO.
Let me know if this works for ya all... via posting here, if you would...
