I too find the apparent 'Freezing' rather irritating, but since, for me, it is
not a real freeze, and frees up when the Command finishes, I just generally
live with it.

I have sometimes used Actions to avoid the problem, but that is usually
inconvenient, and more trouble than it is worth.

If I remember correctly, this was far less of a problem with Windows NT before
Windows XP?


On a more practical note, you could try the occasional Dialog.Beep in your
program for an alternative indication of whether it is really frozen, or just
progressing slowly.


Cheers

Robert
