Selecting FL_ROUNDED_BOX for the up/down box of a Fl_Menu_Button results in some unexpected behaviour.

The menu gets rounded corners (as expected).

The item highlight becomes rounded as well (unexpected, but not unacceptable - although it would be preferable to make them independently controlled).

The main problem is that when the number of menu items is more than can be comfortably fit on the screen, there are some unwanted drawing effects.

If you scroll down to the bottom of the menu, then you will get the rounded corners, but you will also get the vertical borders being drawn to the bottom of teh menu, rather than stopping tangent to the rounded corner.

The same effect happens if you scroll back to the top of the menu. It kind of looks like the top of Batman's head - rounded with two pointed ears on the sides.

Top of menu     Bottom of menu

We'll look at fixing this in 1.2.
