Hello,
A number of users report "System Error 1400: Invalid window handle" when
starting an application. Call stack shows that error pops up in the moment
of showing main form.
Most annoying fact is that I cannot reproduce an error whatever I do on any
computer I try (including virtual machines). Searching the internet doesn't
help as I found a several different reasons, but non of them applies to
this situation. First of all, it happens on small number of computers, but
it seems that it happens regularly on each of them.
Any pointer or idea where to look would be much appreciated. Thank you in
advance!
Best regards,
Vladimir
