I don't have any idea Thorunn, I've run into a similar situation where my ZIP program (in this case Tug ZIP, not sure if this would apply to others), associated Minion's file type with it's ZIP extraction functions.

This is caused by the Java plugin either not being installed into your web browser properly, or it simply not existing.
