When trying to open a file via the file menu - after clicking on open the menu disappears and the program locks. When I try to press anything I just hear a pling (typical fail signal). I can not even close the program down without using windows task manager. Where the program however is reported to still run - no message like "not responding".
some general hints,
independent of PVD and how this situation happened in your case ...
This looks like a typical situation on my system when using some other programs:
during the operation (in this case opening the selected file) some error happened and there is a notification in a new small window which takes precedence before the program window (a "modal window"), but because of some cicumstances it appears
behind the program window or
outside of the screen. Thus you are in some deadlock situation: you can't operate the program while the small window is active (which results in a "pling" when you try anyway), and you can't properly operate the small window without seeing it. Since the system sees the program as "waiting for action on the modal window", it is reported as "running".
what i try to do in similar cases:
- look whether the main program is active (colored title bar)
- push ESC or RETURN to confirm/abort whatever the modal window tries to tell you (without seeing it; before clicking the main window)
- do this series of actions to move the window: ALT+space (this opens the system menu on most windows), ENTER (to activate the first menu option), move the mouse (the modal window should now be glued to the mouse and you can move it around to someplece where you can see it.
- if this didn't work try again with ALT+space, Cursordown, ENTER (in case the system menu has move as second option instead of as first option)
- most of the time, modal windows are opened in the center of the screen. thus i resize or move the main window before doing the critical action so that the center of the screen is not obscured by the main program window.
