Partition editor in install not working as expected

[microsoft_blows at comcast.net]

Ran in VM. No problems. 

Tried to install on a pc along side 12.04.2, partition screen doesn't respond well. On the second attempt, I was able to move the partition, but the Continue and Back buttons stayed disabled. When mousing over the advanced parti tion manager, the cursor changed to the hand, but could not click. I erased the drive, and installed.
