Then it's completely changed the definition of oblique...
I hadn't actually looked at the help or the documentation for DXP (or tried
it myself) however an oblique angle is simply an angle with isn't a multiple
of 90degrees...

So it doesn't select any 60degree tracks or any other tracks than just the
45degree multiples??

wow...  I guess the programmers from protel really didn't study any maths or
geometry.
