I've successfully updated the kennonsoft menu to reference fop2 instead of fop1 by changing
/var/www/html/welcome/.htindex.cfg
changing:
1,panel,./panel,Flash Operator Panel,ico_fop.png

to:

1,panel,./fop2,Flash Operator Panel,ico_fop.png

I use firefox and it worked fine. Trying it out on a worker's computer though, it locked up Internet Explorer. When I tried IE on my computer, it locked it up as well.

Going to http://mypbx.com/fop2 works fine though.

Any ideas what is going on?

Updated to IE 8 and all is working well now.
