In recent weeks my Squirrelmail has been freezing for about 5 seconds every 30 seconds or so. If I'm in another browser window when it's doing this, I'm unable to open the SquirrelMail window until the hiccup is over (though sometimes it appears as a blank window). This behavior pervades all screens in my SquirrelMail, including Options. If I'm editing a message, the input does not echo to the screen, but is buffered apparently as pure text without mouse moves, and appears on screen after the hiccup.
I think this happened after I set the QuickSave Auto Message Save and Recovery to 0 in Options/Display Preferences. I have since reset it to numerous values between 1 millisecond and 1000 seconds, with absolutely no change in the hiccup behavior.
I'm using XP Home and IE with the latest service packs.
Anybody know how to fix this?
