Hi Sandbox,
I can't use the applisations part of the site either, from Mozilla 1.5b on Linux.
I noticed in the links there are references to .dlls, asp - (asp scripts can be written for global access, but they indicate a microsoft mindset), and xml. (xml also has a global standard, but if the site creators are M$ groupies, they may not have coded things for global access.
The site seems to belong to a consultant type, who is able to provide access to government funds. They may fall under the requirements to provide universal accessibility. If this is true, they are definitely out of compliance.
I would complain long and loud if you need this site. I'm sure we can add our voices to yours if you go unheard.
see ya
