below is the error message I received when about 2/3 of the process is done.
Where in my code I sould look for?

Thanks

The CLR has been unable to transition from COM context 0x1afa18 to COM
context 0x1afb88 for 60 seconds. The thread that owns the destination
context/apartment is most likely either doing a non pumping wait or
processing a very long running operation without pumping Windows messages.
This situation generally has a negative performance impact and may even lead
to the application becoming non responsive or memory usage accumulating
continually over time. To avoid this problem, all single threaded apartment
(STA) threads should use pumping wait primitives (such as
CoWaitForMultipleHandles) and routinely pump messages during long running
operations.

Larry;
I think you're pointing me to the right direction.
However, teh instructions won't help.
I created this myProject.mda.config and put in the debug folder. Still got
the same error:
<?xml version="1.0" encoding="utf-8" ?>

<mdaConfig>

<assistants>

<contextSwitchDeadlock enable="false" />

</assistants>

</mdaConfig>



Any ideas?



Thanks again



Bill
