I recently installed PL/SQL Developer on a Windows 8 machine. When I click the preferences button, I can't see the preferences screen. Since it is a modal window then I can't access anything from the main screen. The only way I can close the program is to use the task manager. I've tried uninstalling and reinstalling, but that doesn't solve the problem. Is there a way to reset the preferences window location so it comes to the front and is centered on the screen?
