[GRASS-user] Thematic Vector Problem 6.2RC2

[Alex Bond]

Hi,

I'm having problems with using thematic maps in Grass 6.2RC2.  If I try 
to display *any* vector thematically (including the spearfish dataset), 
then I get the following error:

can't read "lineht": no such variable
can't read "lineht": no such variable
     while executing
"expr {$lineht * 2}"
     (procedure "GmThematic::tleg_item" line 19)
     invoked from within
"GmThematic::tleg_item $mon $id"
     (procedure "GmThematic::display" line 73)
     invoked from within
"GmThematic::display $node $mod"
     ("thematic" arm line 2)
     invoked from within
"switch $type {
         group {
             GmGroup::display $node $mod
		}
		raster {
			GmRaster::display $node $mod
		}
		labels {
			GmLabels::disp..."
     (procedure "GmTree::display_node" line 7)
     invoked from within
"GmTree::display_node $n $mod"
     (procedure "GmGroup::display" line 22)
     invoked from within
"GmGroup::display "root" $mod"
     (procedure "MapCanvas::runprograms" line 63)
     invoked from within
"MapCanvas::runprograms $mon [expr {$mymodified != 0}]"
     (procedure "MapCanvas::drawmap" line 38)
     invoked from within
"MapCanvas::drawmap $mon"
     (procedure "MapCanvas::display_server" line 9)
     invoked from within
"MapCanvas::display_server"
     ("after" script)

Anybody got any ideas or workarounds?  I think this may have already 
been posted under grass 6.3 development - apologies if this is a 
mis-posting, but I could really use a quick fix!

Thanks
