Windows out of reach

[Helge]

Some program-windows I have used with multiple Displays is out of reach when I use only one Display. Who can I move them back to the visible area ?
I can only see them when I hold/press the Icon in the dock (with Spaces disabled).

When you use multiple displays, wherever you leave an application window open, that is where it will show up next time you run that application. So, to prevent this from happening in the future, simply drag the window back to your main monitor before you quit the application and turn off the second monitor.

Problem solved; If you get this problem, quit the program, go to Library > Preferences, find the programs´ .plist file and move it to the trash. Open the program, and a new .plist file with the windows in default position is automatically created.
