Cancel button does not work properly in ProgressMonitor

Question

The cancel button does not work properly in my ProgressMonitor.
Only the keyboard Enter key is accepted but no mouse click.
Everything else works fine.
What could be wrong????
Thank you!

Answer 1

Yes, there is a monitor.isCanceled() and it works if the enter key is pressed. However, a mouse click on the cancel button does not work!!!
Please help.
