Re: NSBezierPath geometry question...

Many thanks for your reply, much appreciated. Is this
something I am doing wrong in the calculation of my
radius, or the placing of the corners (or something
entirely)?

This still has me stumped on how to correct it... If
anyone knows of a remedy, I would be very grateful.

Many thanks again,
Keith
