Thanks for the prompt responses!
Yes, as of now, nothing can be dragged from FARR into an open Outlook message window.
Also, I think, everything can be dragged from FARR into a windows explorer window, and everything can be dragged from an explorer window to an open Outlook message window.
Funny thing is, I seem to remember that perhaps FARR drag to Outlook message was working intermittently a while ago (i.e., immediately after setting up the new machine). Not certain, though. If so -- a possibility is that maybe one of the forced (Win 10, after all) Office updates broke this functionality?
Incidentally, I have Teracopy installed on my machine. That couldn't cause a problem, could it?
Anyway, I do hope you can help figure this out.
Waitingl... and thanks again.
