Hi,
IupPopup starts a new message loop that will return only when one of the
following occurs: "a callback returns IUP_CLOSE, IupExitLoop is called, or
when the popup dialog is hidden, for example using IupHide".
It looks that you are doing it right, but this: "IupHide never returns
and all following events are handled inside IupHide." Is quite weird. There
is no message processing in IupHide, but IupFlush is called. So pending
messages are processed. I noticed you have a timer, it may process the
timer and call the timer callback.
If this does not help you find the problem, then to be able to reproduce
the problem here I'll need a small example code. For instance, you can
change one of the pre-defined samples.
Sorry for taking so long.
Best,
Scuri
