Yes, Yankee clipper is good, and that was my choice for years, but it is limited to 200 copies at a time, and (i think), the size of the copy, whereas clipboard diary is unlimited (options) in both. Only drawback is that one cannot search the database (which can be moved) using Windows search or (better) Agent Ransack, or (as far as i know) converted to regular text.
Another option for me is that of Text Shield, an advanced replacement for WordPad, which does things Word Pad or maybe Jarte and similar freewares will not do. If i set it to autopaste, then it will copy continuously, and save it in RTF automatically (options). I would have place it in the startup folder to load at boot.

Huh? You really lost me with that sentence.
