Zipping Files from another drive fails unless you manually ChDrive first

In mZip.VBZip, if the BasePath is set, the current directory is changed. However, if you're zipping on another drive then you need to change the drive also using ChDrive unless the path is a full UNC path. My solution was simply:

If Left(m_czip.BasePath,1) <> "\" Then 
   ChDrive m_czip.basepath
End If

inserted after the chdir line. you might want to put in a more all-encompassing solution though!
