Hi Antonio, Thank you for the reply. I'll investigate a little bit, and report to you.

Assunto: Re: [Iup-users] Possible regression with iup 3.22? Hi, I tested here a few applications in Windows XP 32 bits and they worked just fine. This call stack is not helping either, because it is not making sense at all. But that's expected since it is trying to show a dialog that was just destroyed. From the code you sent, it seems that the name is not being removed after the dialog is destroyed. I added this code to bigtest.c: IupMainLoop(); ///////////////////////// IupDestroy(dlg); dlg = IupGetHandle("BIGTEST"); if (dlg) { IupShowXY(dlg, 100, IUP_CENTER); IupMainLoop(); } ///////////////////////// IupClose(); And it worked ok in Windows 10 and in Windows XP. The name is correctly being removed. It seems that the problem is elsewhere in that dialog. Memory invasion provokes these weird situations. I suggest you to try to isolate parts of the dialog/code to be able to identify where the problem is really happening, and if it is inside IUP or inside the application.
