Nope, all configured correctly.
Heck, you'd have a completely unusable system without it. Couldn't have more than 2 screens open.
As I said, usable is in the eye of the beholder.
256 colors is too slow for my tastes when using aga. Period.
That doesn't sound right regarding your two screen limit. What resolution are these screens and what are they? I also have no complaint regarding speed of 256 colour modes with FBlit, but like you say, it depends on individual tastes. 64 colour screens I found plenty fast even when I was running a 68020 A1200 with Fast RAM only.
