Twice now, I've gone idle for a few minutes (bio and getting a drink, for example) and I come back to find STO minimized. When I un-minimize it I just get a black screen, which in a few moments crashes with this error:
Fatal Error: There is not enough available video memory (E_OUTOFMEMORY) while creating a render target. Please choose lower resolution settings, or close other graphics applications. Technical Details: size 3072 x 2048 (RTEX_NULL), 7.67 GB RAM, 740.26 MB virtual space available
I then click ok and for a moment I get a Cryptic error window but when I try to do anything with it, like type in text, it disappears.
EDIT - this is when playing this weekend on Tribble doing the Tholian episodes.
