My PC (laptop) has no lights for disk activity - I never see blinking disk lights.

I have the Event Viewer open. Ran my program until it stopped with the Not responding message.
No new event raised under Administrative Events. System logs just have Info events - no warnings or errors.

Never recovers from a hang, but it does allow me to close the Window with the X. Windows message saying the application is not responding. Says: Do you want to end this process? I end it OK.

After ending still nothing noticeable (to me) in the Administrative or System Event Viewer.

I have an index routine in my program. Sometimes it hangs at different places during the indexing; sometimes it goes all the way through. I see no indication of high CPU or disk usage by anything else. My program just gets stuck, with apparently do disk thrashing.

Tomorrow I'll try on another PC.

Any other ideas?
