I'm not sure I consider this a bug as such, but I know the feeling when you think you can get something from history to find you didn't have the clipboard history cliplib open.
I have recently setup TextPad so that the cliphistlib opens when opening TP - and I also have TP in Win Startup so it is always open. Hey, voilà- never miss a previous clipboard entry.
Having said that, I've found the number of times I actually want to drag something from history is very few and far between -- and because of the 'Can't put it back on the clipboard' oversight, it's gotta be a big chunk of text for me to go to the hassle of inserting into a document and cutting it back out.
As an aside, at work I have the cliphistlib positioned so that it hides the Lync/Skype "So-and-so is typing a message" message so that I don't feel compelled to sit, watch and wait until I receive said instant message...
