garh...
it's not just the gmail notifier.
i've just tried to log in to my uni outlook portal, something i've used loads and loads. normally the dialog box pops up with my uni ID and password but it was blank. if i open the drop down box there's nothing in there. i saved and went in no probs, then closed down and tried again, lo and behold, no password details!
so, to summarise.
now, gmail, uni webmail not saving usernames and passwords in the dialog box.
