Hello,

I have applied a fix to CVS for the behaviour described below. The 
callback to redraw the togl canvas was only drawing the coarse surface. 
This redraw applies to changing desktops, resizing, etc.

It is now set to draw all selected features (surfaces, vectors, legends, 
labels, etc).

The file to update is togl_cb.c in visualization/nviz/src .

Please test to see if there are any side effects from this fix.
