Using Excel 2003, I have a VBA program that I use to do Monte Carlo
analysis. Sometimes I run it for an hour or two. My one gripe with it is
that it hogs the whole machine and makes it difficult to use other programs
in the foreground. Generally I run it at night and don't care, but
occasionally I need to run it during the day.

Is there some way to tell VBA to limit the machine time it burns -- to force
it to pass off XP's multitasking off to the next task? Or to tell XP-Home
to limit how much resource gets allocated to Excel?

Thanks.

Bill
