unable to save ROI file / error message: please help

Hi Dominique,
The "echo $QT_PLUGIN_PATH" command line returned nothing (i.e. a blank line, so I guess there is no path set for this then).
cheers,
Rv

Ok, indeed, in this case, there's no need to unset the variable.

Could you try to set QT_DEBUG_PLUGINS before starting Brainvisa:
export QT_DEBUG_PLUGINS=1

At Brainvisa startup, you should see message about Qt plugins that are loaded. Do you see plugins that are not in Brainvisa package ? Which ones ?

Could you also have a look in /etc/xdg, you may have a Trolltech.conf file here. if so, could you tell me what is its content ?
