Actually, it is the scroll-margin that does it.
When the menu is created, point is at the last line.  Since you have 
scroll-margin set to 1, it scrolls up.  You can't see that because you have no 
indication, but on a graphical terminal you can see that the scroll bar has 
moved a bit.  Unfortunately there is no way to scroll the window, it is either 
select something or C-g.  wid-edit.el tries to set a scroll-other-window 
command, but it somehow fails to work because of the default binding to 
keyboard-quit.  And in any case, IT only scrolls down, not up.

So, the menu created by wid-edit.el should either (or both)

1) place point somewhere else, preferrably at the end of the first line.
2) provide a way to scroll the window. tmm-menubar does this so it can be done.

Someone familiar with wid-edit.el must look at this.
