Agree - even though NO Operator actions are occurring - there is still plenty that Could be occurring. I've seen the issue - even with wording of "Application Not Responding" appearing at the top of one of our apps here as its running. Although - at the time - its doing data processing - or data retrieval from MS SQL. So, maybe it's one of these "behind the scenes" events that are occurring - like you mentioned below - but, its one that's running into a little bit of issues and taking TOO Long to run - and Thus the Blue Circles...

It blinks the cursor, it repaints the screen. If any tables are open, they are cached. It checks to see if its ON ERROR or ON KEY handlers should be triggered, it checks for menu events. It checks for Window messages, which might be telling it to refresh, resize or shutdown. Finally, it yields its control to the OS. If any of these events get "stuck," Windows may interpret that as a "busy" app, hence the spinner, or even an "Application Not Responding" issue. So, maybe no operator actions are occurring, but LOTS of stuff is going on.
