The menubar will not display in full screen

Question

Hi.
I have a strange problem in fullscreen mode, on my Macbook pro 15"
I LOVE fullscreen, and infact the next macbook I will get is the 11" air because of its size and because full screen is so nice to work with.
But I have a strange problem which I can't find a solution for.
Suddenly the menubar will not display it self when I move the mouse to the top of the screen. The only way I can access the menu bar is by exiting full screen (ctrl + Cmd + F) and the toggel it back on after I have used the menubar
This actually makes fullscreen mode useless and its driving me nuts, because this should not happen on Apple software. I would expect these sorts of behaviour on windows but not in osx.
Anybody have a hint about what to do?

Try this:  make a temporary, backup copy (if you don't already have a backup copy) of the library and 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. 
Click to view full size
3 - launch iPhoto and try again.
NOTE: 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.
