strange behaviour: sometimes sites appearing in popups
I've noticed some very strange (buggs) behaviour w/ my mozilla:
Sometimes it shows websites (ie. when opening links in a new
tab by middle-clicking) in a new window - without any toolsbars
or menus etc, and the new tab remains *unpainted* - not blank,
but really unhandled. when clicking a link in the new window,
the site normally goes back to the viewer in the new tab and the
popup is closed.
This doesn't happen quite often, but if once an tab is affected,
some others (in the same process) are affected too.
After restarting mozilla, the problem goes away for a long,
