the fire thingy that animates ( freeze test) sometimes stops moving if you open a window and drag it on top so it covers the flame. To get it moving again I have to drag the IBT window "off screen" and then back on. Seems to just be a visual bug, the benching never gets affected, but since it looks like a freeze, not sure if this can be fixed. I have an nvidia 9600gt video card, latest drivers as of 6-20-09 and running vista x64 sp2 not sure if any of that matters.......
