I'm using Pads layout 2.5 to design my 4-layer PCB. I want to place increasingly larger circular keepouts in each of the layer. The drafting toolbar for placing keepout shows options for all layers, top, bottom, both layers, and the individual inner layers, but I can't seem to be able to place keepouts in the inner layers (they disappear after I hit ok). Keepouts restrictions are trace and copper, copper plane, and vias and jumper.
Any ideas why? Thanks in advance.
