You can hover over the icon but if you click it, it does not work
I can't reproduce this using modern.ie on IE9. When I hover the options display and when I click an option (eg, 'make it flat') it is applied. Clicking on the gear does nothing, but I don't think it's supposed to.
@mattab in ie9 you won't be able to click on the popup, as it will be closed, as soon as you will move your mouse to point the link. I confirmed it, and it's not working on ie9
Thats correct. Had a quick look at that right now.
Guess that might be a CSS issue.
In IE9 the li's are getting a style="width: 0" which breaks the layout.
It is caused by an IE7 fix which is also applied in IE9:
Maybe it would just be enough to check if 'html' has the class 'old-ie', which will only be the case for IE < 9.
Btw. has anyone tested that on IE8 or IE7 ?
