Hi,

I had this problem a number of times in the middle of long edits of big
spreadsheets and ONCE accidentally found the way out, which of course I
can no longer remember. The problem seemed to occur as a result of a
failed drag-and-drop, which failed due to premature release of the left
mouse button while dragging. Can happen when you have a hiccough.

Now I'm trying (with a blank sheet open and all others closed!) to
re-create the problem, which was indeed something to do with a latching
selection of some kind. But it's not the right-hand mouse button and
it's not the wheel...

best regards,
