Google+1 and Stumbleupon behave badly in IE
Using SM Toolkit 2.0
Google+1 and Stumbleupon are not behaving properly in IE.
In IE9, the icons appear but the whole "toolkit" disappears when they are moused-over.
In IE8, neither icon appears.
In IE7 they also act weird, although I don't remember exactly what weirdness they do but it's similar weirdness.
All work okay in Chrome, FF and Safari.
See example here:
printA.asp
Just mouseover the globe icon/share
All help and hints appreciated!
