In my application I have a row of buttons (for BBcode) that is included in various places. Each button is an empty div with fixed dimensions, a background image and an oncli
I've found the solution. It was the "float:left" attribute on the buttons that made it fail.
Which is rather strange because in all the other places where this code was included, it also had the float - and it worked. Even in IE8.
Anyway, removing it and using "display:inline-block" for the placement did the trick.
