[PARRAT Hélène <helene dot parrat at cea dot fr>]

Good morning,
We  have and old application that oblige us
to launch xwin with the option -depth 8 as "-emulatepseudo" is no more
available.
I have a pc with windows 2000
launch xwin with the command :
XWin :0 -xkbmap fr -query machinename -ac -depth
8 -fullscreen -emulate3buttons -clipboard -from pc-myname

when I'm connected i launch matlab 6 in a dtterm
matlab -nojvm
when I do a plot it crashes cygwin
Here are the traces
