The first time I invoke Solver, it runs just fine, finds a solution, etc. If
I try to run it a second time, nothing happens. Solver doesn't start, just
nothing. If I close and reopen the workbook, Solver still won't run. If I
close Excel, and reopen the workbook, Solver will again run, but only once.

This has not always been the case. It use to work just fine.

I am running Excel 2003/SP2 under Windows XP SP2.

Any help is greatly appreciated.

Thanks,

Charlie Almquist
