Inconsistency displaying IDLgrROI [message #59788]

Dear All,

The sample of code below is supposed to convert some data to an IDLgrROI
and then display it. The STYLE=0 keyword is supposed to cause the object
to be rendered as a series of points.

This works well when I am connected to the workstation through a VNC
session; however when working directly on the machine's console, it
appears that the STYLE keyword is ignored, and the object is rendered as
though it were a IDLgrPOLYLINE.

Does anyone what would cause this behavior? I am somewhat new to object
graphics, but am learning quickly.

Thanks,
Bill

orois = objarr(num_rois)

for i = 0, num_rois-1 do begin
tmp = (*ptr_seeds[0])[i]
// *tmp is [ n x 3 ]
orois[i] = obj_new('idlgrroi', $
[ transpose(*tmp) ], $
style=0, $
thick=4, $
color=[0, 255, 0], $
alpha_channel=.4)

endfor

omodel->add, orois

xobjview, omodel
