I have been trying out the Free version of Tigra Menu and have found it to be a very useful utility. I have had a look at the demos of the Gold version and I have found that it seems to have a bit of a problem when icons are added, this slows down the draw rate of the menu. Is there anything included with the gold version that enables you to turn on picture caching so that all the pictures used in the menu are pre-loaded, thus speeding up the drawing of the menu items?
Tigra Menu GOLD improves initialization time in DOM enabled browsers by using dynamic element generation so items not initially seen are not created until they are requested. To preload menu images you can use well know techiques (for eample in 3d buttons demo - see items.js file for preload code)
