I had contact with the helpdesk, send them a drawing with 20000 layerfilters, they "solved it" and put it in the last update.
My questions is: who knows how I can delete layerfilters (that originated from Autocad 2006)? Autocad 2010 has the command "layerfilterdelete" but DS doesn't even see the layerfilters.
(ps: how do I paste a screenshot it this message?)
