Hmmm,

We have actually seen more Javascript issues of late with Safari over
FireFox and I.E.

I've had specific Javascript problems with IE 7 that weren't there  
with IE 6; I've also had other Javascript problems with both IE6 and  
IE7. Unfortunately, I don't know enough Javascript to tell you what  
to look for, but I do know that there are issues...

I don't know whether it's a case of Firefox and Safari using non- 
standard protocols or the other way around... I have my suspicions  
though! :)
