I took the step of converting most of the fonts from cufon to @font-face with the exception of a few items (I tried with the main menu (at the top) but it didn't look very pretty).
The left menu (category) is working fine. No issues when hovering over that submenu anymore. Instead, I'm encountering a situation where now the main menu submenu 'pops' (hover over 'Products' on this page) on an internal page instead of flows open (like it does on the home page) and selecting when hovering the submenu disappears. It happens sporadically.
I was thinking this would be a jQuery conflict, so I check the code on the home page---jQuery is only loading once (1.7.2) and 'noConflict' is loading as well. On the internal pages (like the 'Nuts' page form the link above), jQuery is loading twice because the online store needs jQuery, but so is the 'noConflict' scripts. So I disabled the store's loading of jQuery. Cleared my browsers caches and the same thing happens. The submenu 'pops' open on the internal pages and disappears when attempting to hover over it in IE, Safari, and Chrome. FF doesn't seem to be affected all the time. So now I'm wondering if it's not really the jQuery conflict, but something else?
bChandler: you might have a point, though I have yet to try it. I will test your theory.
