One of the rather odder bugs. OOo’s file menu suddenly appears for no good reason (while playing embedded video in Firefox on another workspace). Story is that OOo has the focus while the video is playing in totem-mozplugin, totem-mozplugin seems to want to inhibit the screensaver from kicking in so sends regular Left Alt strokes to the display via XTest. If OOo has the focus, it receives the Alts, and one of its quirks is that the file menu appears on press and release of Left Alt.
