Right click doesn't work in Firefox 3.6 and FileVista 4.1

I am doing a demo of FileVista 4.1 and have a client using a Mac with Firefox 3.6 

Her left click on the left side (folders) works perfectly.

But she cannot right click on the files on the right side.

Any suggestions as to what could be the problem?

I just noticed the demo site does the same thing. I FileVista doesn't work properly on a Mac?
