Well, if it's just "sitting on a screen waiting for input" then there are lots of things going on: VFP runs its own event loop, it's checking for keypresses, checking for any timers running, it has a READ EVENTS loop running on top of that. 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. _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://mail.leafe.com/mailman/listinfo/profox OT-free version of this list: http://mail.leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/CACW6n4tSX1x745n+sy=ic-hfzajo5yd3_xfuvoz-nv9qqcs...@mail.gmail.com ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
