Hi Luis, welcome,

This is because on Macintosh, buttons don't get focus (by default), but 
on other platforms they do. So when you click the button on Windows it 
steals focus from the field and you lose the selection.

The easy way to stop it doing this is to set the traversalon property of 
the button to false. Then it won't steal the focus when clicked.
