Is there anyway to have Excel via VBA do a repetitive calc while a userform
is showing? So when I say:

Userform.Show

I want to mimic what would happen if I held down the F9 key. Now this could
either be based on:

1) a Loop with a timer
2) or it could be continous (triggered after the .show Method) and disabled
when I press a command button on the shown userform.

Any ideas?

Thanks
