[esp-r] graphical interface problem

[Filippo]

Hi,
I'm working with Ubuntu 10.04 and I have an nvidia quadro FX1800.
Running PRJ (ESP-r command) in X11 or in GTK I have some problem with 
climate and simulation module as graph windows flickering and graph 
disappear when I try to resize the windows. Furthermore I can't use the 
capture option.
Is the graphical interface a little instable or is there anythings I can 
do for make ESP-r working better?
Thanks,
Filippo
