Opening Startup Disk hangs my system

[Crotonmark]

I have tried everything I can think of and it hasn't helped.
I have a 2010 iMac with 8 GB RAM.
I am running OS X 10.7.1 and did a installation over my previous Snow Leopard installation.
I had an existing boot camp partition under SL and on the Windows side I am running Win 7. I have no issues on the windows side.
When I open System Preferences and click on Startup disk there is a grey "circular" icon that spins. Previously this would stop and I would click on bootcamp and boot into Windows. Now this icon keeps spinning and I get a beach ball and this causes:

1 - The startup disk app to hang
2 - The dock to become unresponsive
3 - Command-Tab to stop showing me open apps.

I then need to power off to get back to normal.

I have repaired permissions. I ran verify disk and got an error so I used an external drive (big mistake as I lost the use of the drive for other functions) and created a recovery drive. I ran Lion recovery and it said it repaired the disk successfully. However, I am still having issues with System Preferences/Startup Disk.

Does anyone have any suggestions on what I can do?

I am also a MAC newbie and at a total loss.

TIA

Mark

Open Console.app and see what the logs say it's doing when it hangs.
