I'm using Xtreme 4.01 and would like to know how to make rounded rectangles that have *fixed radius* corners (rather than proportional to the size of the rectangle).

I figure this is a super common thing to need to do but I can't seem to figure it out. I've tried changing the curvature property by adding 'pix' at the end (like it shows for the width and height e.g. 12pix) to specify pixels instead of the default 0.2 but am having no luck.

I assume I'm missing something mind-numbingly obvious. If somebody could take a second to point me in the right direction, I'd appreciate it.

Thanks!
