1st only firefox, now safari too.
Have to log back in (to dashboard) after almost every change made and frequently changes made to a widget for example, won't register, have to refresh page and log back in. Very frustrating!
Tried clearing cookies, exceptions, etc out of firefox, to no avail.
Tried deactivating plugins
Updated to latest install of WP
read lots of forum posts that suggested replacing wp-admin.php or whatever, but none of those trx or fix worked for the other questioners, so...?
