Compiled into a class file, which is very small and therefore quick to load, this application is excellent. Assuming your site has loads of buttons that are essentially the same, except for the text that is on them, this will dramatically cut the loading time of your page and remove the need for you to keep making new buttons. The app just uses the bare untexted buttons and puts the text on for you! Two buglets that I have notice are that the buttons stay on the very top layer of the document, so if you have floating layers that do not completely cove the button, the button will overlap the layer, and second, the app puts a status bar message as the mouse goes over the button. However, it only flashes briefly at the bottom before disappearing! Nevertheless, I am still using it on my site in preference to rollover buttons.
