Yes. That's a bug that occurs when resolving the layout frame in the proportional layout. The 2 pixels are the border widths not considered correctly for fixed-height/width frames. I will investigate. :-)

If you want to even avoid clicking the expand button in a dialog, what are good average widths for an item? Even for more than 20 characters?

It looks like it is 2 pixels short for height.  If the size list size is between 5 and 15, it will include the vertical scroll bar to scroll for those 2 pixels (or, I am guessing, however big the list box boundary line is).

It looks like the width is short by the padding size before and after the text - maybe adding an $m width to the horizontal size would make it better (or figure out what the right padding + list box boundary line width is and add it in).

close enough.

Let the width of List Chooser try to accomodate better to the actual size of the string.
