When I open any session in session manager, It suddenly closes and when I check my task manager I can see HeidiSql but not responding.
Session not opening and not responding
Perhaps HeidiSQL's main window is on another screen which is now disconnected?
You can try to reset the window positions:
Exit HeidiSQL, start regedit.exe and reset some values to their originals:
- go to HKEY_CURRENT_USER\Software\HeidiSQL
- delete all values starting with "MainWin", as shown in the attached image
- restart HeidiSQL and hope to see it
That should not happen. If you fear of losing something you can make a backup, in HeidiSQL, under File > Export settings. Then, install the newer version. Don't uninstall the old one.
If HeidiSQL is still not responding then, please give it a few minutes to show. There seem to be sporadic file lock problems with auto-restored query tabs. v12.3 warns in such cases with a message dialog once the tabs are loaded.
