Thanks for the Beta key. I tried a few times to get the password by loggin into the ClipCache forum and submitting a request, but a response never showed up in my inbox there. I'd be curious to know how you went about getting it.
As to the program itself, I find it's actually far better than I had thought. I'd been using PasteLister by Progency Software, an extender which, to my mind, still beats anything going even though development has stopped. Among other things PasteLister allows you to pick one or several clips via a pop-up menu by holding down the control key as you select. It then pastes back into the active application in the order in which the clips were selected. It also allows the insertion of TAB and ENTER keys to clips, handles bitmaps, allows clip folders and is low on system resources. It is, however, beginning to show its age.
To my surprise the pasting tab in ClipCache 3 does allow you to output keystrokes to specific windows, a process which is both heftier and more limiting than PasteLister.
