Minor Screensaver Problem

[Bob Agel]

This certainly falls short of critical and cannot be faithfully
duplicated so a bugzilla is not in order, however I've found that
sometime this week my screensaver has developed an annoying habit of
suddenly starting in the middle of an active project. Moving the mouse
or typing will immediately revert back to normal, however this does
happen several times per day.  Any things I might look at for a
correction?
