I had mixed success with earlier versions of ClipCache Pro but this latest version seems to run really well under Vista.
It is great for improving your efficiency and generally making life easier – it is also occasionally useful for those moments when your brain becomes disengaged and you delete a mornings work
Ease of use, custom keyboard short cuts, images getting clipped as well, clean up tools to remove formatting
Some common code I use to dump data to spreadsheets uses the clipboard, if you leave clipcache on you can easily get 1000 + new clips in its store !
Some crashes under XP
