Hi, I just saw a difference between 21.4 and 21.5 about live windows. I managed to reduce the code down to this below. ---------------------------------------------------------------------- (defun my-test (args) (interactive "e") (mouse-set-point current-mouse-event) (let ((release-window (selected-window))) (message "Window: %s" release-window) (sit-for 1) (read-string "### ") (if (window-live-p release-window) (select-window release-window) (message "Window: %s not live" release-window) ))) (global-set-key '(control shift button2up) 'my-test) ---------------------------------------------------------------------- Procedure: Make a split screen {C-x 2}, press (control shift button2) in one window and then drag the mouse over to the other window and release button2, so that a (control shift button2up) event is generated, and my-test is executed. The result of running my-test is that the second window is not live in 21.5 but is live in 21.4. The intervening call to read-string, using the minibuffer, is important for causing this difference. Maybe beeing in the minibuffer for a while The second window is visible all the time during this operation so how come it is not live anymore? Is this a bug in 21.5?
