I verified this on my workstation and we're looking into it. It seems
to be some sort of interaction between our main launch script and a
local application we install on top of Matlab to monitor usage. I don't
know if or when we'll be able to fix it but I've found another workaround
besides the only you've already found ("don't use -tty"): if you launch
Matlab directly from the version locker instead of from the base locker
it doesn't seem to show up. i.e.:
add matlab_v6.5; matlab -tty -nosplash -nojvm
Thanks for reporting this.
