Re: need help on protel dxp DRC Warning - Pad/Via touching p
House_Cat seems to be used to DXP so perhaps he knows better.
I beleive a bug exists in the DXP software which causes an error when vias are on the edge of a defined plane. in some cases a via intended to join to the plane will be reported as a broken connection and in others a signal via will be shorted.
Have you tried to relocate the vias so they are not on a plane boundary line?
Just a guess.
