Indeed, it is very annoying that one cannot copy-paste directly from page source to the PTA. It seems some invisible stuff is put together with the selected Diagram description onto the clipboard, when you copy from a page source page, on which the PTA then chokes. So far I have not been able to figure out what it was, because attempts to print the offending stuff apparently left it invisible. Next week I will make it print what was pasted as a list of hexadecimal ascii codes, that should reveal what was hidden in it, and then I can add code to automatically remove it. That should restore the ability to copy directly.
