This feels so weird that I feel I must be imagining it, but some non-zero chunk of the time, Handy seems to paste the clipboard into the window rather than whatever I've just said. Sometimes it happens a few times in a row, so there's clearly some trigger, but I haven't worked out what it is. I think it might be intense processor use as that's been the case on at least one of those occasions, but I'm guessing.

This is on OSX 15.5 and Handy otherwise works beautifully.
