In that case, it shifts from mouse-set-point to handle-switch-frame which selects the new frame. Is this shift due to the transient-map map setting in mouse-drag-track? Eli, if you could point me to where the switch-frame event is generated when the click is in another frame, with that I might be able to produce a temporary fix for this problem. It would also help if in handle-switch-frame, the handle-focus-in hook invocation occurred after the call to do_switch_frame rather than before; then we could grab the value of the newly selected frame rather than the old one. Bob tBut I can't find anywhere in the Emacs 25 code where mouse-1 is bound to handle-switch-frame. Can you point me to where this is coded? Is the keymap in use changing? Is there any way to capture a switch-frame event and attach my own handler to it? (I guess I could redefine the primitive handle-switch-fraem
