(The commented-out line sets the minimum width of the menu.)

Unfortunately, I don't know how to fix this one. The problem is in
setting the minimum width of a pop-up menu in Windows. If anyone knows
how to do that properly, please let me know...

For now, the extra line you see is MrEd's hack to make the menu as wide
as requested. MrEd adds a sufficiently wide, very short, disabled,
dummy item into the menu.
