Bevel Modifier problems

Hello,

I have noticed 2 problems with the bevel modifier:

  1. The ‘width’ variable only seems to vary from 0.00 to 0.05. Any amount above that makes no different when I use it. Am I missing something here?

  2. When I add segments to the bevel, it seems to change the smoothing of the whoel mesh.

Any help would be great thanks.

Problem 2 was solved by removing all smoothing from the mesh, but Problem 1 persists!
