Glad I'm not alone here!
I've not been able to log on to PPRuNe Chat from home for several weeks now, although no problem at work.
My thoughts : could be an 'old browser' problem - I've got Java script enabled, but my version of IE is 3.5-4 years old - do I need to update? Alternatively is it a Zone Alarm conflict? I've got a cookie crusher programme running in parallel and get cookie warnings plus notices for Zone Alarm blocks. Could this be my problem?
Come on you PC Gurus - I'm getting too much sleep without access to Chat
