this regressed in 1279...
At least when I first put in 1279, when I first happened to notice, it looked like it wasn't working.
(And I thought, well, that's that.)
But then later, I noticed it was working & I wasn't able to duplicate?
Now I'm thinking, it might be a focus (or similar) issue?
What I did notice, later, was...
[menu item] (F)ile was "indented" (not selected, just indented)
& in a situation like that, focus is (though certainly not obvious)
on (F)ile, so at that point, this mouseover issue ensued...
maybe ? that is also what happened, initially?
(Also thinking that ... there might be some relationship in there with "ghosting
", maybe not? And/or, CANCELMODE
[I'd much rather have Alt+TAB working correct vs. a possible oddity here.])
