What is Borderline - The End of off-screen Apps?
How it works? Just run it. Borderline should be needed only on occasion, so it's meant to be run on demand rather than to be running continuously in the background.
A Window is Not Visible
Some applications (window) have a habit of appearing not visible outside the screen.
Borderline takes all windows that fall off the edge of the screen and moves them back into the screen bounds. For multi-monitor systems, each window can be moved to a specified screen or can be moved to rest wholly on its nearest screen.
The "Lost windows syndrom" can happen when applications remember their last window position between runs and if the desktop resolution or monitor configuration changed in the meantime. This is not uncommon with remote desktop when the client and server have different screen resolutions or monitor configurations. This sometimes also occurs if a system changes its desktop resolution frequently, such as when Tablet PCs change their display orientation.
Or some applications don't behave well if the taskbar is docked to the top- or left- edges of the screen.
Or maybe you want an application window to be aligned exactly to a screen edge.
