hi andreas, i'm brand new to this board, but have been trying out the jquery for a while now. i can't seem to get the same results you're describing, on a mac anyway.
but you should preload those roll over images for the icons. or better yet, use the css 'sprite' method. basically you have both the off and on state in one image. then move the image with css when you roll over it. you define the height, width, overflow:hidden, etc in css. you'll be able to find alot of info on that on the web. there's some load time when you roll over your icons, that might be effecting the clueTip? hope that helps a little. gary.
