So how many of you experienced guys have seen that message before?

I am attempting to do a gnd copper pour with the polygon command, but
get this error message. Can someone suggest the steps to follow in
identifying where the invalid polygon might be. The screen recentres on
the middle of the left vertical boundary of the board layout ... and
there is nothing at that location.

Would appreciate some clues please. And yes I have been successful using
this technique on other boards so I think that I have the fundamentals
correct.

Regards,

Ross

Solved! I do not understand why ... but a seemingly unrelated and
unrouted top layer signal seemed to be the problem. When I saw its tiny
little nose poking out of the corner of the screen, I routed it and then
the copper pour went perfectly.

Thanks for reading.
