I have an app with two timers. Timer1 does some data-related work.
Timer2 just backs up up the data files into a zip archive. Now a
situation happened where Timer1 is running and opened a table. Then
Timer2 started. Then in Timer1 SetRange is called on the previously
opened table. An exception is raised "Cannot perform this operation on
a closed dataset.". But the table was open and Timer2 does not close
or open any tables just puts them in a zip file. What could be going
on here?

I do notice DoHandledLogin was called and a dialog was shown modaly
from RemoteLoginDialog.

Do any of the tables that are being used in the timer(s) have any data-aware
controls connected to them ?

I tried to cancel this post but I guess it didn't work. I resolved the
problem myself. The tables I was using were created dynamically and I
forgot to set the correct session.

No problem.  AJ Marknette was kind enough to modify our NNTP server a while
ago to add this capability, but unfortunately it is something that I have
not had a chance to put in place yet.
