I don't think you can get around it on the P400: 2 text channels means
that no more than 2 rectangles outlining a shape may overlap. This isn't
a bug, it is a feature apparently inherent to the machine's architecture.
It actually says so in several places in the Software Command Description
manual. For some reason the bits don't get ORed, as one would expect.
