Thanks,
I can open my links on my version of IR and Firefox but some of my students my students get this message when they open this link as an example.
The .swf download and plays in IE for them but half way through the movie the movie will stop and the following message appears:
Debug Error
Program: C/program files/ Internet Exprorer/ IExplorer.Exe
abnormal program termination
The it shuts down completly
