Also...I'm running into a problem when I try to do "see open-package" - I get an "Unhandled Exception":

0 > see open-package 
: open-package
  create-instance dup 0= if
  3drop 0 exit >r strdup r@ >in.arguments 2! (lit) (lit) then
  Unhandled Exception 0x6f70656dffffe000
PC = 0x00000000ffd10e3c NPC = 0x00000000ffd10e40
Stopping execution

Maybe this has something to do with me trying to view the function outside of its execution context, but just seems weird that most/all of the other ones work fine, and this one generates this error.

This is actually the bug I picked up on earlier which Stefan has now 
committed to SVN as r613. If you "svn up", you should find that this bug 
has gone away.

HTH,

Mark.
