For some reason, my Stickies (a free -like app that comes with Mac OS X) seem to sometimes want to wander off-screen. I first saw this after I started using a dual monitor system at work. Stickies often appear partially off-screen when the external monitor is not attached.
To fix:
- Quit Stickies while off-screen
- Resize the Display (use System Preferences, I recommend the smallest display size available)
- Start Stickies (you may want to make some change, even just dragging a window to a new position
- Quit stickies
- Resize screen to normal resolution
- Restart stickies
Stickies should be on-screen now.
Tested with 10.3.8 on a Powerbook.
