Popups not shown

[Andreas Daetwyler]

When I call the function MessagePopup(...) the message sometimes does not pop up immediately, but only when moving the mouse cursor or pressing a key on the keyboard. On my PC it works perfectly well, but when I run the application on another PC (with the same operating system) this problem occurs.

Used software:
WinXP Professional
Measurement Studio 6.0 LabWindows CVI

Has anybody an idea what the problem could be?
Thanks Andreas

Hi Andreas,
have you checked whether calling the ProcessSystemEvents() function directly before calling MessagePopup() helps?
