Comment #7 on issue 602 by mwlochb...@gmail.com: xmonad hangs when clickJustFocuses = False and the user clicks outside of the focused window while a submap is active. https://code.google.com/p/xmonad/issues/detail?id=602 If you return (All True) from your event handler, then the event will be left on the queue (unless I've badly misunderstood something?). peekEvent lets you handle the next event regardless of whether it's one that xmonad cares about, but if you just want to use the submap for keypresses and abort on mouse events then handleEventHook seems cleaner to me. -- You received this message because this project is configured to send all issue notifications to this address.
