It does not matter what limitations a dependent claim (like claim 120) contains. The independent claims are the claims that have the "allowable" subject matter. Claim 120 depends from claim 114 which contains the limitations:
"A method for displaying representations of objects in a graphical user interface for a computer system, comprising the steps of: displaying a plurality of icons in a row, where each icon represents an object in the computer system; displaying a movable cursor via which the user can select individual ones of said icons; magnifying the size of at least one of said icons as said cursor is moved into the vicinity of said one icon; and repositioning others of the icons along said row to accommodate the magnified size of said one icon."
All the limitations in claim 114 were considered allowable over the prior art; claim 120 has nothing to do with the allowability of the application.
