Hmmmmmm

That shouldn't happen, because if windows_app
is set to  nxdesktop_helper then is should be blanked or
ignored

eg

My version of nxdesktop_helper has (had actually) (sic) :-

# windows_app is brocken - bug.
[ "$windows_app" = "/usr/bin/nxdesktop_helper" ] && windows_app=""

        rdesktop . . .  -s ""  a.b.c.d

doesn't complain about the blank -s switch value.


The Ubuntuers remove the -s switch completetly in theirs
which is better.


so

???? what's in your nxdesktop helper ???

??? what is your distro and rpm etc version  ???


A certain amount of patching is necessary in some distros
to get the application entered in
        "Run application" in "Session Type" 
in nxclient "windows setting" to actually be passed
to rdesktop.

It always will be if you have an unpatched

         nxserver / nxnode
