Sounds like your "background" task runs in the main thread. This
prevents events like keyboard input, mouse clicks, GUI updates etc. to
be processed until your task is finished.

The usual way would be to run all GUI stuff, i.e. your dialog, in the
main thread and any lengthy calculations in another thread. "lengthy"
might be something around 3 seconds processing time on a 366 MHz box.
