Want MOVE, get COPY

Old problem came back. I didn't do anything just started working one day and ....

I select a Note. Type M (alias for Move). Click from, Click to. Note is moved. BUT it's still there in the original location, just like a copy.

Similar result if I edit a note. Let's say I double click a note to open the editor. I Enter a line break into the top line somewhere, the line wraps. I click away and the operation is complete, except, the original version prior to my edit is still there in addition to the edited version.

In both cases I am able to erase the unwanted copy, but of course would like to avoid that.

Clears up if I close DS and doesn't happen the first few times, but evenutally starts again.

What up?
