Has anyone experienced problems with knotify messages that do not disappear? The "View" and "Ignore" actions in the message window do not work. And if the screen saver has been activated, the same area where the knotify message had once been persists as a featureless gray box. It will not redraw unless I log out and in again.

It's not too big a problem, but since the message box is above all other windows, that little gray area becomes a blot over all other windows.
