Menu icon Foundation
F5 topbar.js crashes IE9

I'm not really looking to support IE9, but I'm facing a situation where Foundation5 actually crashes IE 9 (At least in the virtual machine I'm using - ModernIE/Vagrant). Haven't seen this crash in IE8.

I'd be happy showing users a "Browse Happy" banner with whatever other degradation comes with it and leave it at that, but crashing their browser is not something I want to do.

I've tried any number of combinations of enabling/disabling javascript. Removed all custom js, removed all foundation components, removed all other scripts being loaded, but the moment I include topbar.js back into my build - my IE9 crashes.

I have a staging site at http://longbongo.com, if anyone has any ideas I'd really appreciate it.

Never heard of this happening and I searched through GitHub and the older forum posts here and SO. We QA on real IE9 machines here before each deploy. Wish we had seen this so we know how to help more.

Wasn't able to get to the site. Do you still have an example?

Did you add any custom logic to the menu?
