In using the Maple 17 VectorCalculus package I was suprised to find that the Norm of a free vector is not the same as the Norm of a "corresponding" RootedVector, i.e.the same vector with a different root. Am I missing something ? Thanks for an explanation.

restart;
with(VectorCalculus):

P:=<1,2,3>; # free vector
PP:=RootedVector(root=[-1,2,-3],P)

Norm(P);
Norm(PP);

Can anyone tell me how to scroll the context menus in Maple 17?

I'm using the DynamicSystems pkg and would like to use its context menu but it's cut off at bottom of screen.

When I right click on an expression in a Maple document, I get the context menu,but it goes off the screen at the bottom, and I can't find any way to scroll down to see what is cut off.   I tried the Zoom feature on the menu to make things smaller, and it made the print in my document smaller, but the context menu is the same size, and still gets cut off.

Any help appreciated.
