When JTextField has set InputVerifier which shows dialog (reporting invalid
input) and user puts some data into such text field and then clicks on button,
the button remains in pressed state after dialog is closed. When you roll mouse
over the button. If mouse pointer is outside of the button, it looks normal. The
button sometimes behaves correctly in the first click onto button. Next try
always brings described behaviour. It is the same on WinNT 4.0, JDK 1.3.1.
