Well the card is an ASUS so I have their fairly current feb 2005 ati drivers. Had zero issues. Will check on drivers tho. Changing drivers around w/o better info is not a good idea. ...it can easily introduce more issues. I did not notice this in beta and no other program is doing this (vue, carrara). Sorry, but I think this is a bug...wanted to know how many others were having same issues. I did play w/ render settings...trying to see a pattern. It acts like it is rendering then blank. When I do 3delight no problem, preview ok. Some scenes aren't doing it, but most are.

No need to think outside the box....
    Just make it invisible.
