A couple of skin attempts and a question reguarding them

First off, i've been lurking around here for a while, and i gottasay i love the portableapps suite(although it has made me get 2 bigger thumb drives now :))

anyway, i thought i'd give a skin of my own a shot and the first results can be found

Lightning

Sub Zero

and

Abstract

please keep in mind i'm sill fairly new to photoshop so they may not be the best.
now on to my question, everytime i try to skin the drive space slider it doesn't show up. is there something special that needs done with them?

EDIT::::ignore the question i just figured it out
