I noticed in 6.14 $shortfn will not return the short filename version ... is anyone else having this problem?

//echo -a $shortfn($mircdirsystem) - mIRC version: $version
D:\SCRIPT~1\system - mIRC version: 6.12

//echo -a $shortfn($mircdirsystem) - mIRC version: $version
C:\Program Files\mIRC\system - mIRC version: 6.14

Anyone know a solution to this? ... it's making mIRC create the "c:\Program" and windows is complaining about that folder being there.
