After the recent 7.14 upgrade, I've noticed that when selecting a file using $sfile, it does not return the file extension.

$sfile(*) = C:\Users\Jack\AppData\Roaming\mIRC\mirc
while it should return
$sfile(*) = C:\Users\Jack\AppData\Roaming\mIRC\mirc.exe

Since I didn't upgrade to 7.12beta, this bug might have been present in 7.12 too. (I've noticed on the 7.12 changelog that an issue with $sfile on Windows 7 has been fixed)
