Hi,

Just downloaded and started the Pega exercise system for the CSSA course.

When I try to do the first exercise in Mozilla, Opera and Chrome, I am bumping against the following:

Any of the Designer Studio Header menu won't collapse sideways and everything I click stay active and won't hide (see pick).

When I try to use IE, I come across the following issue:

Error Code: INET_E_RESOURCE_NOT_FOUND

Please help me out with this, as this is frustrating to work with when you try to make progress...
