"..\scripts\nxTools\nxClose.tcl" terminated abnormally
--------------------------- ErrorInfo ----------------------------
can't read "user": no such variable
while executing
"ExcemptCheck $user $group $flags"
("LOGIN" arm line 2)
invoked from within
"switch -- $event {
CLOSE {
iputs ".-\[Close\]-----------------------------------------------------------------."
if {[..."
(procedure "::nxTools::Close::Main" line 7)
invoked from within
