javascript error on firefox 3.6.22

[AVASA]

Hi,
I'm noticing a Javascript issue with Roksprocket. I'm using the fresco rocketlauncher template with the same setup as your example site. Attached is an image copy of one of the slider failure modes. Just click on an arrow. The first time nothing happens from the user's
perspective 2nd time its as in the attachment. I am using FireFox 3.6.22 at the moment.

The following is the error that causes the observed behavior:

uncaught exception: [Exception... "Not enough arguments" nsresult:
"0x80570001 (NS_ERROR_XPC_NOT_ENOUGH_ARGS)" location: "JS frame ::
http://uskiters.com/components/com_roks ... s/moofx.js ::
anonymous :: line 21" data: no]

Please let me know what you find and thanks for all you help!
Mark

sorry, but there is NO WAY to support all versions of Firefox.
FireFox release channel is on version 15
