When I edit an old post or create new ones, my system hangs and I can't access my server for about 10 minutes after that. I thought that it was only when I attempted to insert images, but that is not the case all of the time. I upgraded to 2.2 and that didn't help. I also "disabled" all of the plugins. I using a HS connection, Pentium IV and using Windows XP Professional. It doesn't seem to matter whether I use I.E.7 or FireFox.
