This has bothered me for a long time. Finally I got some clue,but without solution, from SAS website:
http://support.sas.com/kb/18/248.html
Can not SAS provide some solution to this bug?!
This was a known issue in EG Version 3, but was addressed in EG 4.1, and as far as I know, it's not a problem in any later EG release. SAS is not providing hotfixes for EG 3 (originally released in 2004) these days, as we've had 3 major releases since then (EG 4.1, 4.2 and 4.3).
