I didn't know about that version. Now that I do I will use it. Thanks!

Sorry. I forgot about that. I run Mac OS X 10.2.8 build 6R73 and 
openmcl 0.14.2-p1 (soon to be patched).

I guess I don't really need openmcl to recognize the variable in this 
case, since I only pass it on to cocoa to setup my toolbars.

Anyway, thanks a lot for everything!
