Space Bar Pauses
 

works very well except space bar pauses the screensaver it does not invoke the menu. Vista x64 Ultimate, ATI Radeon 2900,cpu=wolfdale 3.0, 4 gigs memory.

Could you try switching to Windowed mode (F key) and see if the space bar brings up the menu?

windowed mode does indeed bring up the settings

Somehow the settings box is getting trapped behind the Aquarium screen when in full-screen mode. Vista 64 Ultimate is so weird in so many ways, that we may just have to drop it from the Recommended Equipment list.

But it doesn't seem to be a problem with Vista Ultimate 32. (SP1)

Yeah, it's always been the 64-bit version where they changed everything. That's the one which uses that whole SYSWOW folder nonsense, too.

Using Vista 64bit here and pressing 'space' brings up the settings panel fine in full screen and window mode.
