Right clicking behavior - bug??

[Jkoseattle]

About once every couple hours of working, all of a sudden I can't click on anything anymore, because the left mouse button starts acting like the right mouse button. So whenever I click in the stage, Moho wants to drag instead of selecting, as if I'd clicked on the right mouse button. So at this point the left and right buttons behave exactly the same. I've tried lots of things to try to get out of this state, but nothing seems to work short of closing and restarting Moho (which isn't that big a deal because the startup time is so fast -- thanks again, SM, that's impressive and never fails to delight). This has happened to me on multiple systems. There appears to be no obvious cause for this that I can tell - happens at random. Or maybe it doesn't, but I haven't discerned the cause in any case. Has this happened to anyone else? Thought I'd post here before filing a real bug.

do you have a mouse and a digitising tablet? is there a wire straying near / across the tablet active surface??

Nope, just a regular tower with a wired mouse, and the other is a Surface Book with a Bluetooth mouse. It has the stylus, but I don't need to use that to make the bug happen, and it happens with the old tower too.

When that happens again, try hitting all your modifier keys to make sure they aren't being read as "held down".
