I have two problems with swing components.

1� The fisrt JOptionPane I call is not large enough for the text, and
the text is not completly written in it (it ends with "..."). The
problem disappears from the
second time I launch a JOptionPane with the same parent frame.

2� I'm using a JMenuBar, and when you click on one menu Item, I open a
Frame (JFrame). The first time I click on a menu Item, the window
appears but is reduced immediatlty. The problem disappears from the
second time I use the menu bar.

Do someone know where it can come from ?
Thank you for your help.
