I think it has something to do with how they track focus events. I think that depending on how the window manager orders things, sometimes when switching windows/desktops, Firefox receives Focus Out events with the NotifyWhileGrabbed state (i.e. the window manager has a keyboard grab during the focus change. Any other application could also have said keyboard grab. Firefox ignores these focus events even though they should not, and so it gets confused thinking a window still has focus when it does not.
That seems to be what's going on anyways. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
