> I've found that calling cgArrow with the /SOLID and /AddCmd keyword doesn't work in adding a (solid) arrow to a resizable window. I think this is because the call to cgColorFill in cgArrow (lines 233 and 234) does not allow the parameter to be passed. I tried to fix it by adding '_Extra=extra' to the cgColorFill call, but that also doesn't work because /AddCmd is not allowed in the call to cgColorFill.

Well, something is screwy, for sure. The solid arrowhead is being drawn,
but not in the right window.

I do notice that this works correctly, if you use the WINDOW keyword, as
the documentation specifies, rather than the ADDCMD keyword, which is
not defined for this routine. :-)

I presume this has something to do with the ADDCMD keyword being passed
along with _EXTRA. It looks to me like Coyote wrote this routine. I'll
see if I can get it sorted out.

Cheers,

David
