Hey @VehbiEmiroglu I have been seeing this quite a lot while doing some extensive development in samba for the last few weeks. I have seen it with the dlg.AskQuestion in scripts and with ask question actions. I have also noticed in some rare cases the show message or ask question showed behind the samba ui and locked up the whole system since its locked to the prompt behind the sambapos ui. I have seen it in different databases, different computers, and in the last 2-3 versions of samba.
At first that square box let me type text in it with my keyboard but after starting the task manager and switching to different ui screens it locked up completely and is now not letting me do anything on samba or on the box… system is completely locked up.
After closing the prompt window by hitting x on 2nd samba item on taskbar, samba crashed and showed the following message.
