I found a solution for IE9 and Windows 7 and I'm happy to share it with anybody else that may be having this problem. This is how I fixed it.
1) Go to Extensions, Template Manager, Select MyCommunity, Edit
2) Under Parameters change the Variable or Fixed Width Layout to "Variable"
If for some reason the middle column is still misaligned in IE9 follow these steps:
1) Open IE9
2) Click on View and Compatibility View and enter your website into the list
3) This will fix the problem
*I hope this saves you time and frustration...
