May i ask if your Library's shortcut is on the start menu left or right pane?
If it is on the right pane....guess you're getting old.....
Maybe you would like to try this: ( serve the same purpose )
Double click your computer, on the left pane drag and drop the Library Folder into the start orb.
It will be pin to the left pane of the start menu
Hope you don't mind if i switch your Library shortcut from the right to the left side.
