text opacity - won't save, causes crash

[John Oram]

Hi everyone-

I'm having trouble with the opacity of text objects in v4 (and earlier betas).

I have no trouble setting the opacity of a new text object.  However, 
Graffle doesn't seem to save the opacity setting - when I open the 
file again, the text is completely solid.

I have also been seeing some serious weirdness when I try to change 
the opacity of text that I previously tried to make transparent. 
Often Graffle quits completely, or just refuses to let me change 
anything else on the screen.  I get this alert:

	*** -[NSColorPanel set]: selector not recognized

I'm having no trouble at all with opacity of graphical objects, just text.
