I'm on WP 2.9.2, I still remember the days when navigation within wp-admin does not involve java(?) and it was fast.
For some unknown reason, I keep experiencing extreme slowness while doing tasks that involve any screen changes while posting, searching, editing or opening new tabs withing the Admin dashboard.
The pauses/hangs would last about a minute between the time when I see the screen, and until I can actually do stuff within that screen.
Because of this, a post that can take 15 minutes to complete can take an hour or more, if it involves going through old posts to add stuff to the current post.
What can I do to fix this? I'm on the latest Firefox.
