Marek,

It sounds like your application is an ideal candidate to have the time
consuming operation run in a worker thread, leaving the UI thread to
do updates.

Don't try to do the UI from your worker thread - that quickly gets
messy. Instead post a user defined message to your UI window and have
it perform the display operations.
