-lineNumber Option does not work

[Jodscho]

Hey nice project, finally a dmenu-like program for windows :)

The -lineNumber Option does not seem to work for me.

Running wmenu -elements "one,two,three,four,five,six,seven,eight,nine,ten" everything works as expected:

If i add -lineNumber 4 to the previous line no elements show up:

(The more i increase the fontSize the less elements appear, e.g.:)
wmenu -elements "one,two,three,four,five,six,seven,eight,nine,ten" -fontName Arial -fontSize 14
