FF 4.0.1 has stuffed up Sugar CRM

[Boppy]

Sugar CRM CE 6.2.0 will not let me add drop down boxes in Firefox. Yes
I've cleared the cache. Yes I can do what I need in IE8. Yes the
server permissions have been checked by the web host.

IE8 was partially faulty but works since the host reset my
permissions.

Initally I got this errror:


User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/
4.0; Tablet PC 2.0; .NET4.0C; InfoPath.3)

Can anyone suggest a fix for FF so I can stop using horrible IE?

Thanks in advance,
Jo
