I recall a few others talking about problems they had - mostly I remember ATI cards, and mostly it was fixed by updating drivers.

You say you have the latest. Others who are familiar with ATI and the driver releases may suggest that what you think is the latest may not be, so it's probably a good idea for you to say specifically which version you're using.

The other possibility is that the latest might mean something that just came out a few days ago and you're the first to use it and find out it is broken and may have to go back to the next-to-last version.

On March 31st, somebody posted that "ATI just came out with a new update that fixed" his Poser problem with the screen going wonky when the mouse moved over the preview. Now that was a few weeks ago, so maybe you want to try a driver that was released at the end of March.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
