Odd GUI behavior (Windows

Show all headers | View raw

  To: comp.lang.java.gui
Alright all, I've got a doozy that's driving me nuts.  I'm afraid I
can't post code since this is from a very, very large application but
I'm hoping someone will find the problem familiar and give me an idea
of where to start looking because I'm stumped.

I'm working on maintenance and feature addition to a  large
client/server java app.  The client runs on remote machines (requireing
JDK 1.4.2, old I know).  It connects to a Jboss server which does work
and retrieves data stored in a database.

The client connects to the server, requests certain data, displays it
and allow sthe user to edit the data.  It then pushes changes to the
server where they are stored in the database, rinse, repeat.  On Linux
(Redhat) and Windows 2k everything runs well.  However a few of our
people are seeing strange behavior on Windows XP  (SP2).  JLists in
particular are not drawing their contents properly.  The server is
being queried for the contents, they are being returned and as far as I
can tell they are being added to the JList. However it continues to
display "blank" to the user.   On SOME of our systems adding a forced
repaint() call after the last element is added to the list solves the
problem.  On other systems however this seems to have no effect.

I've also seen strange issue where certain portions of the GUI were
suddenly taking up much, much more room than they actually require
(large blank areas pushing components out of place).  I'm not sure if
this is the same issue or not.  I've made sure the data is actually
getting to the client, made sure all events are happening properly.  I
can't see any logical reason for this issue and the fact that its
happening only on XP native XP (my VMWare install of XP that I use for
testing displays NONE of this behavior).  We thought it might be a
graphics card issue but all computers are using the same graphics card.
 

Any ideas?  Where the heck should I be looking?
Chris
