Lost Parts

I am brand new to modeling and I am working on my first project in Gmax so excuse me if this is a stupid question. Unfortunately, I ran into an interesting problem lately. I had a wing done and decided to hide it in order to work on a part of the fuselage. After finishing up what I was doing on the Fuse, I tried to unhide the wing. Nothing happened. I have hit every single unhide button I could find to no avail. The part, named "WingL" shows up on the parts list and I have even tried to do Edit->Select->By Name and it selects the part but no brackets around the part show up, etc. What could I be missing? Any help would be appreciated.
