Thanks Helen.
The problem seems to happen when you return to the application after
switching to another task or if the application has been idle for a
period of time. The error message is sitting there when the screen
appears. And it happens on stand alone machines as well as when
using a server. I have never seen it happen when actively using the
application.
The app has a timer that refreshes the data displayed in a grid
every minute in case someone adds a new record but this doesn't seem
to be the cause. I put a try - except around the refresh but it
doesn't trap the error.
If I knew what the error message means it might point me in the
right direction.
Regards
Bob
