Hello,

I updated my application to the latest version AC 9.19

Unfortunatelly now the application crashes sometimes, randomly. It is very hard to reproduce it.

Hopefully at least the stack trace of the exception will be handful:

Hello,

as far I know and everytime I have checked the logs, it seems that it crashes during closing (hiding) form.

Also as you can see it here in this log:

…..

[0009EC4A] Forms.TCustomForm.Close (Line 5607, “Forms.pas”)

[0030E067] _clientforwardtest.TForm40.Timer3Timer (Line 111, “_clientforwardtest.pas”)

….

In this case it happend during automatic closing of one popup window, it was closed by timer.

But this error occured also for another forms/windows, closed manually by button.

Just guessing, could be by caused by too quick of form closing? Extended borders, Animations are enabled – showing/hiding, could it be that form is closed during the animation? But it is in one gui thread.

Unfortunatelly I was not able to identify the specific moment or situation what it is crashing.

It is IM application, main window, chat window(s) (with blinking) and autoclosing notification popups and “bubles”. It is crashing quite randomly – usually without user action, so when popup is showing/hidding itself.
