My apologies if this subject has come up before or if indeed in newer versions of PTPA this is now possible.

I find that the single biggest drawback at present in using PTPA 11 is that you can only have a single project opened at any one time. Not only that, but there is -to my knowledge-no way of transfering a track from one project to another using the clipboard even if the first track is closed.

Contrast this say with word processing programmes where many users will have several documents open at any one time between which copy/paste operations are quick and easy.
