General help

Hi.

I have installed Moodle 1.1.1 on a Sun Solaris box.  Everything (well, mostly)works great and we are very excited for our courses to go live in a month.  Just yesterday we tested the site on many different browsers and platforms.  We found a consistent problem with IE on Macintosh - 8.5, 9.1 and even X.2.  On the resource pages, the top frame will not load (containing the description, bread-crumb-trail and jump menu.  The bottom frame loads fine with the uploaded file.  Has anyone else experienced this?

Does anyone have any suggestions of what to do?  I've redownloaded IE (latest version) for the Mac and still it doesn't work.  When I look at this site moodle.org, through IE on the Mac machines, the resource top frames load and look fine.  Thus, it must be a problem with my installation.  Any ideas would be appreciated. 

Thanks.
