Nuke - 2009-03-02

Using FM from 0.81.  Presently on RC1.

I can't get Freemind to have any printer margins.  I have read some posts to select margins in Page Setup menu after selecting "Fit to one page".  But, this illusive menu or dialog box never comes up on my MacBook.

Where am I to find this menu for setting page margins?

MBP Intel, OSX 10.4.11, Java 1.5.0_16

Thank you for your help
