ClipSafe Clipboard Backup - description from Softdepia.com:
ClipSafe backs up data copied to the clipboard, protecting it from accidental erasure. Your computer's standard clipboard can only store one piece of data at a time.
Without ClipSafe installed, whenever you copy new data to the clipboard, existing data is lost. ClipSafe begins monitoring your clipboard automatically when you log in to your computer.
Conveniently restore clipboard data using an icon on the system tray. ClipSafe includes a viewer to preview data which has been backed up. Dates and times when backed up data was added to the clipboard are also retained.
Customers receive free software updates and technical support for ClipSafe through Multimedia Australia's exclusive www.SupportBase.NET service.
ClipSafe Clipboard Backup is a "Free to try" program. You can download and try it for an evaluation period.
