314 | other kinds of events (focus changes and button clicks, for | |
315 | example), or by XQueryPointer calls; when one of these happens, we | |
316 | get another MotionNotify event the next time the mouse moves. This | |

8398 | bar handle, we want to let them drag it down all the way, so that | |
8399 | the bar's top is as far down as it goes; otherwise, there's no way | |
