Oh interesting, thanks. Certainly not ideal though. And I don’t see why that affects behavior within windows of the same process.
What is interesting is the difference between different invocations, eg on the BP editor: dragging from a pin works, right click does not. There are a number of similar popups through the editor with similar consistent inconsistencies.
IIRC from when I debugged this it appears there is some sort of race condition that causes this, and ends up with focus not being set as far as the keydown handler is concerned. Unfortunately having a breakpoint seems to tip it to always work after stepping/resuming.
