The code that's causing this is (when (input-pending-p) (setq edebug-stop t) (setq edebug-execution-mode 'step) ; for `edebug-overlay-arrow' (edebug-stop)) because when you're tracking the mouse (and you move it), you'll have input pending, I think? Hm... No, it's not that simple -- just moving the mouse before calling (foo) also triggers this. Hm! This gets stranger and stranger. Here's a simple test case: Move the mouse (don't click it), and then eval this: (track-mouse (input-pending-p)) I get t. If the last mouse action is a click, then it evaluates to nil. Right. Move the mouse (don't click) and then evaluate: (track-mouse (when (input-pending-p) (read-event "foo: "))) =3D> (mouse-movement (# 892 (863 . 529) 1948101423 nil 892 (57 . 17) nil (398 . 19) (15 = . 30))) So `track-mouse' will give you the previous mouse movement? OK, that's fine I guess. But back to the original problem: (input-pending-p) is non-nil here, but it's because of a mouse movement, which edebug doesn't care about. I guess edebug really cares about unread-command-events here? So changing the call to just examine that instead might be the fix? --=20 (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
