We have had a number of problems recently with Meebo. One suggestion from Meebo is to renew the source code used by your browser. It certainly helped for me. The suggestion was to first clear your browser’s cache (see the Meebo link at the end of this note if you need help), connect to the meebo home page i.e. http://meebo.com and holding the control key, press F5.
Full details are at Meebo.
I presume this is something we might need to be doing if we log in via the Meebo site but not if we log in via Pandion?
Is it something we need to do on the public computers or are their caches cleared automatically?
