menu popup as real tiny

[John Taber <jtaber johntaber net>]

I've created a simple menu popup over an eventbox just like the tutorial but 
when I right-click the menu appears as a tiny 1 mm box even though it has a 
menuitem with a label of "Resize".  Could it be related to the eventbox 
containing an image ?  Anyone experienced this or have ideas how to fix ?   
thks.
