Preventing program from freezing a couple of sec

[beier]

I have a function started by clicking a button. It takes some time to run, however while running, the program freezes up, and doesn't update labels until it has reached the end.

Is there any way to prevent the program from freezing while running a function, or some way to have it update labels?
It is updating a progress bar, but everything else is frozen. Can't move the window either.

Try calling Application->ProcessMessages() periodically within your function.
