So it sounds like the issue is that pinentry-gtk2 grabs the keyboard but
not the mouse?

I can confirm that i can use the mouse outside of pinentry-gtk-2 while
it is up with the keyboard locked: left-click, drag-to-select,
middle-click paste, etc, all seem functional even in non-pinentry
windows.

But the keyboard is still active only in pinentry-gtk-2 -- so maybe
escape or enter would let you dismiss the dialog?

that said, maybe pinentry should be grabbing the pointer as well as
grabbing the keyboard?
