Thanks a ton for all of the help AJ, Al, and Gary. I basically took did what AJ and Al suggested, including replacing the GVimPortable runtime with the official one.
I forgot that the vimfiles directory under $VIM doesn't contain any files, so I simply placed my vimfiles dir there and also placed my _vimrc in the same directory. Now everythign works exactly like I want it to. Thanks again! Tom Purl
