IPhoto 09 and 11: spinning beach ball of death when accessing contextual menu.

Question

Whenever I right click to access the contextual menu, iPhoto gives me the spinning beach ball of death. This happens only when I right click on a photo from the events in the iPhoto library. It freezes for a few seconds then the spinning ball appears.
This happened in iPhoto 09 so I upgraded to iPhoto 11, but the problem is still there. I have deleted all files from the previous version before installing iPhoto 11 but it didn't solve the problem. Those files were application support files, cache and preferences all in the library. I have even created a new library in iPhoto 11 and imported a few photos just to test it out, but the problem persisted. I just can't right click without having that spinning beach ball of death appear. The only solution is to force quit the application. This is very frustrating and I would appreciate any help.
I am running Mac OS X Mountain Lion.
Thanks

Try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
     User/Home/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iPhoto folder (Snow Leopard and Earlier).
or with Lion and Mt. Lion from the User/Library/Containers/com.apple.iPhoto/
Data/Library/Caches/com.apple.iPhoto folder
3 - try to launch iPhoto and check for any improvements.
NOTE 1: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto.  You'll also have to reset the iPhoto's various preferences.
NOTE 2:  In Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
