I have a Dell XPS 210 PC with Windows Vista and an older Dell Dimensions 3000 with Windows XP.  I teach a course using mroom.  My uploaded files (whether Word, PowerPoint or web addresses) open immediately with Windows XP, but it takes forever for me to open those same Moodle files of mine with Windows Vista.

I have all those same files on my Dell XPS 210 hard drive and open them immediately, and that same PC of mine accesses the web immediately.  So my problem seeme to be solely openning material on the Moodle platform?? 

Is this a Vista problem, a Moodle problem, or something else.
