(4-pixel alignment actually) Yes if it doesn't cut too much into the performance of the convertors.
Do you mean that windows are aligned on 4 pixels boundaries, or is it just the width that is a multiple of 4 pixels? The former will in fact speed things up (even more so on 8 byte boundaries), whereas for the latter, the MMX code is already ~5% faster :) The non-MMX code will sufer a slight penalty since I'll be needing an extra register.

I agree, but this will need revamping the windowed and the GDI drivers. Moreover, this is not doable for the overlay driver because it hasn't got any backbuffer.
Is the overlay used by default? If not, we can put a note in the docs. If it is, then I guess we'll have to go the way of other DirectX program...
Oh, and Allegro doesn't crash on Win2k when switching resolutions, it just displays a black screen and accepts no input. You can still click on the [x] to shut it down.
