Thanks Leigh.
Actually I was more looking for a reason why when you have called
form1.close (or equiv) that an application would not actually close?? This
is very intermittant. I would say about 1 in 200 times it will not close.
The form has direct-x controls is doing a lot of memory management and
taking a lot of keyboard input, it seems as though it is almost getting so
tied up in knots that it does not get the message to close.
Is this possible?
Matt.
