I'm pretty sure this situation affected my FUS: on one of my profiles I had downloaded an old OS 9 game (tailgunner, that cool vector arcade classic) that auto-switched my display, then promptly crashed on me. Whatever you do, don't try that game!
When I FUS instead of displaying an animated cube, Tiger now displays the previous desktop briefly, then switches to the next active one (we like changing our desktops).
I'm actually trying to GET THE CUBE BACK 'cause I actually like it (yeah I know, getalife) and am seeing weird articles on dragging colorsync profiles into something you can only call up by typing a command in Terminal.
Here is the link, but be forwarned, it didn't help me...

There has to be some more reasonable explanation...
