I think you have an old Allegro version: I fixed that in 3.9.30. There's 
still only one mouse driver, but it mixes DirectInput for fullscreen with 
GetCursorPos() calls for windowed mode, so that works fine now. I think 
we have to go on using DirectInput wherever possible, because without it 
you can't get accurate mickey-mode input.

You had problems with the mouse moving too fast? For me it's the 
opposite: when you run your program in a hires mode, it goes way too 
slow. But it's already moving a whole pixel for each unit that Windows 
reports, so I don't know how to speed it up without losing precision, 
unless there is some call to increase the input resolution...

Really? It would be interesting if you could profile this a bit to see 
exactly what part is taking so long, and also which of the various timer 
drivers it is using. That certainly doesn't sound right to me, and it 
isn't nearly so slow on any of the machines that I've tried...
