I've got a 3 state image for the browse button but when I put the mouse over it, it will take about a second and a half to show the hover state. Is this a bug or am I missing something? I'd be fine not using an image if I could have the button height be smaller and the text still be centered vertically and horizontally in the button but that doesn't seem to be the case.
Not sure if this will help, but I found this earlier today in the docs: *Mouseover events are inconsistent in Flash 9 so you may see a short lag when using the rollover option. http://www.uploadify.com/documentation/
use the hideButton option and set the wmode option to transparent. You can then place the "invisible" flash button over the top of any image on your web page. A roll over image for instance. You can also use width and height options to change the size of the flash button. Remember however the flash button must always remain on top of your html image for it to work.
