filled symbols bleed at edge of map

[Ken Lord]

Hi List,

I've seen the same problem affecting legend icons when the symbol is
bigger than the size of the icon, again along the bottom.

-- Turn on the BC Minfile layer, found in the 'Exploration Layers'
folder of the 'Layer Controls' tab.
--Then click the 'Legend' tab to see the problem.

It can also be seen in the larger symbols of the 'Soil Geochem by
Percentiles' layer found in the 'Soil / Geochem Samples' folder of the
'Layer Controls' tab.

This issue has existed for so long that I had assumed it was well known.

Cheers,
Ken Lord
Vancouver BC
