From not responding properly (DoEvents).

[sthrudel@gmail.com]

I use asynchronous call to send bytes to serial port. While bytes are
being sent I call Application.DoE vents().

The problem is that when I try to e.g. move the window or press a
buttom, the from doesn't respond the first time I do it. The buttom
responds (is pressed) when it's pressed for the second time.

Any suggestion?
