Committed:	Thu Mar 8 21:52:06 2001 UTC (24 years, 7 months ago) by pjm2
Branch:	MAIN
Changes since 1.2:	+2 -3 lines
Log Message:	For some odd reason, the drop down menu was unable to populate itself with machine names. This was traced to the is_dir method in PHP which seems to not always do as it should... i.e. return true if the argument is a directory.
