Yes, I know how to overcome this problem. Is there something about my write-up
in the FAQ that is unclear ? Please submit improvements to the faq.

Q1a: How do I make a custom pad shape ? (I need something other than the simple
pads shapes built-in to Protel: "circle", "rectangle", "oval", and "octagon")
A1: Build the custom pad shape out of several overlapping pads on the top layer
(and optionally a through-hole pad on the multilayer). Assign them all the same
reference designator.
A2: For even more flexibility, build the custom pad shape out of overlapping
fills on *both* the top paste mask layer *and* the top copper layer. Place a
small simple pad touching those fills. (Either a surface-mount pad on the top
layer or through-hole pad on the multilayer).
Q1b: I tried that, but when I placed that footprint on my PWB, it lights up
bright green with lots of DRC errors.
A1b: run "Design | Netlist Manager | Menu | Update Free Primitives From
Component Pads" and run another DRC check.

Weird. Did you double-click on that power pin (in the PCB editor) and make sure
it had the correct net ? This sounds like something you need to show to one of
the people that have volunteered to look at possible bugs.
