Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-beta-b15)
Java HotSpot(TM) Client VM (build 1.3.1beta-b15, mixed mode)

Sparc (OS Solaris 2.6):
java version "1.3.0"

1. Start up DialogProblem.main, e.g.:

  D:\jdk1.3.1Beta\bin\java -cp . DialogProblem

A frame appears with a button to pop up a JDialog.
This dialog demonstrates the following bugs:

a. The very first time the contents of the textfield is not selected
on a Sparc, whereas it is on the PC.

b. On a PC the very first time the background color of panel and panel2
of the dialog differs from the rest of the dialog. This does not happen
on the Sparc.

c. If a window of another application is put in front of the dialog
and removed afterwards, the dialog is not repainted correctly. This
happens both on a PC as on a Sparc.

d. If the dialog is closed and popped up again the text in textfield1
is not selected, neither on the PC nor on the Sparc.

e. If the dialog is closed and popped up again the dialog is not
painted correctly, both on a PC as on a Sparc. Again on the PC there
are two different (grey) background colors.
