Did you determine the Operating System because there are some differences using the RUN Command for ex.:

*RUN /N7 gives an RUN Error under WINNT and WIN2K
local lcRun
if atc("windows nt",os())#1 .and. atc("windows 5",os())#1
*WIN9X, WINME
lcRun = "run /N7 start mailto:marvin.blase@isenberg.de"
else
*WINNT, WIN2K
lcRun = '!cmd /C"start mailto:marvin.blase@isenberg.de"'
endif
&lcRun

Hope this helps.
