Cannot access toolbars when posting

I have installed WP 2.7 and am using Coffee Desk 2.0 theme. When posting, I can access the toolbar icons to link, etc. However, I cannot use the wysiwig editor or switch between visual and html. I cannot even see the icons for media, etc. I cannot use colored text, upload from word, etc., like I could in 2.6. Any Suggestions?

In light of other comments in this forum, I tried disabling the firewall protection and nothing changed.

Thanks,

Jack
