This just started happening a week or so ago. When I click on "send direct message," the box comes up but it's moving slightly left and right in a constant jittery way. I suspect it's a fault of something on my laptop or with some program malfunction, something may be failing? But I just wanted to know if anyone else is experiencing the same thing. Nothing else weird is happening with any other pop up boxes anywhere.
I can't take a screen shot because it's in motion. I'd have to do a video.
