I'm currently running through the CD-ROM based courseware for the Sun Certified Java Associate exam. Thought it would be a good idea to get a Java cert under my belt - interesting to see the little differences between Java and C#. (string literal equality comparisons, anyone?)
I did have a problem trying to access the Flash-based courseware in IE7 though - it loaded the index page and I could choose a module, but then when it loaded it just showed an empty window. Tried all the flash perms etc., got latest Flash version, nothing helped.
However, when I ran the CD-ROM under Firefox it ran first time and works perfectly. Maybe there's a subliminal message there, I don't know, but as long as it runs I can live with it in Firefox :)
