MyBB Community Forums

Hey guys. I'm a longtime user of SMF who is in the process of moving his forum to the latest version of MyBB (work in progress). I've sorted out many issues but I'm having a browser specific issue I need help with. I believe it's my sub menu (new posts, community, etc) that is the issue and it's only in Internet Explorer, not Chrome or Firefox.

Here's an example of what's going on:


And here's my forum link:

Any idea how to show that submenu in I.E. the same as it's shown in Firefox and Chrome?

Thanks,
Dave

Anyone know how I can resolve this?
