[Gvsig_english] Geoprocessing Functions::Proximity::Buffer::Problem with dissolved buffer features

[Wolfgang Qual]

workaround:
create a new polygon theme which is larger than the extent of all single 
buffers together, use the clip-function (buffer theme as clip theme) - you'll 
get a theme which will have the shape of all buffers.

Best,
Wolfgang
