What web browser works when check outlook for web access mail

I have tried Mozilla, Firefox, opera, and the built in web browser, but I have having troubles getting anything to play nicely with Outlook for web mail. I can login ok and read messages, but when attempting to create a new message, the to, cc, and bcc buttons are not clickable. Only way to send a mail is to remember the full internet mail address, which is not easy. Work uses it, so it is the only way to check my mail from home or on the road. The exchange server at work is exchange 2000 and I am running Suse 9.1 Pro. Thanks in advance Rob
