Resizable stacks in one direction

[Frank Leahy]

Hi,

I've got two stacks that I want resizable vertically but not 
horizontally.  They work fine on Mac OSX, but not on Windows (no resize 
arrows appear anywhere on the edges).  And I'm now unable to resize 
them on Windows regardless of what I do -- check and uncheck and 
recheck the Resizable check box, "set the resizable of this stack to 
true", change the Min/Max height and width.  Nada.

Any suggestions for how to make it resizable again?  Is there some 
property I don't know about maybe?

Thanks,
-- Frank
