Sometimes when I hit the save button after making some changes my browser (FF) hangs for perhaps 30 seconds +. I often see a message in the status bar that says "Waiting for wordpress.bytesforall.com" then it switches to "transferring data from wordpress.bytesforall.com". Any ideas what may be going on? I took out the Ata footer link thinking that may have had something to do with it but it didn't help.

After a bit of experimentation I found that the "After the Deadline" extension I had installed was causing the problem.
