In my QuickWin program I display a dialog by
l=dlgModeless(dlg)
But sometimes the dialog won´t come up. The thread seems to be stuck somewhere inside dlgModeless, no error message is being given. Sometimes the dialog comes up as it should.
Funny thing: It does make a difference if the .exe is opened in the explorer, run by Visual Studio or opened by a third party program.
This is real strange. At first I thought It would help to compile the solution again - which helped indeed in the past. But now a customer complains that he sees the same behavior. But he uses the same .exe for quite some time.
Does anybody knows this and can give me a hint or how I can track down the error? It can´t be something in the code - because my customer proves the opposite.
