OK, so don't do it then. Try posting a user defined message to the
same window and do the COM object operation in response to that
message - i.e. defer the operation slightly.

OK, 1 last suggestion then.

Rather than defer the operation by posting a user defined message,
start a timer (try some wildly different times to see if it's
significant) and do the COM operation in the timer handler (stop the
timer beforehand of course).

Jolly good.

Out of interest, did you try varying the timer - did it make any
difference if it was short (say 30ms) or relatively long (like 1s+)?
