Since Quicken runs so much faster under plain DOS on the same machine
(yours) what do you think? (;-))
Due to the antiquated hardware design of the PC the CPU has to put the
image onto the Windows screen pixel by pixel and all that via the slow
AT-bus. 640x480x256 - that's a lot of info to be put into the VRAM on
your card (How many MB does that amount to, by the way? I could never
get that right). And that takes TIME.

For a quick fix, try switching to the plain vanilla VGA-driver included
with Windows. That'll only give you 16 colours, but at the same time it
reduces the amount of info on the screen by a factor of 16. Consequently
things like scrolling are a lot speedier.
