Button State Affected by Windows XP Display Settings

Question

I have a reference to a 3rd party class that extends JToolBar. I am trying to set one of the buttons in this
JToolBar to "pressed." I know the action class for the specific button I am looking for so I just iterate across
all the (abstract) buttons in the toolbar's button group. (See code below.) When I find the button whose
action is the one I am looking for I call setSelected() on the button.
Here is where it gets wierd.....
I am running Windows XP and, if I change the Appearance Windows and Buttons mode** to
"Windows XP" style the code works fine (the button gets depressed programatically). However,
if I change the mode to "Windows Classic" style the button no longer gets depressed.
Any ideas as to how the windows mode could be affecting my code???
Thank you,
Michelle
** right click on the desktop and select "Properties" go to the "Appearance" panel and select from
the "Windows and Buttons" pulldown menu.
Enumeration buttons = mapToolBar.getButtonGroup().getElements();
while (buttons.hasMoreElements()) {
AbstractButton button = (AbstractButton) buttons.nextElement();
Action action = (Action) button.getAction();
if (action == MyButtonAction) {
button.setSelected(true);
break;
}

You might want to check with third party who developed the toolbar extension.
I would also try a small test program using only out-of-the-box Swing JToolBar to see if you get the same result.
Hope that helps
