No problem. Thanks for your perseverance :-)

I noticed that on Windows Snow didn't even

No hurry. i am using linux at home, so no problem. i was trying some
things out at work, where i am using windows so that's why i noticed
that.

Ok, yes it's a bit more complicated...

P.S.: When you will be adding ComboBox, could you maybe also add radio
buttons? i think that will better suit my requirements... Or you don't
plan to add anything until JavaFX is released? :-o
