Components aren't displaying under Win2k

Question

We have a Java Applet which opens dialogs containing lists of data from our database, radio buttons, buttons, checkboxes, text labels etc. Since moving to Win2k, the components sometimes don't paint. This is intermittent and, as near as I can tell, random. The list component always displays. The other components still work, even if not seen (if you know where they are, you can click 'em). They can be "displayed" by manually triggering a repaint (move the dialog off-screen and back, minimize-restore, cover with another window and uncover, etc.) Interestingly enough, sometimes these same activities can cause them to disappear again. Even the background color is among the "components" that doesn't display. I've attempted to code .repaint and .setVisible invocations to "force" painting, to no avail.
Any assistance you can provide would be greatly appreciated,
Thanks in Advance
And now, some gory details:
We're using JDK 1.1.8 and Netscape 4.x and Netdynamics (which is no longer supported). Due to previous design considerations, we're locked into Netscape. Due to no more upgrades to Netdynamics, and a glitch in Netscape 6, we can't upgrade Netscape, and are concerned about upgrading JDK.
The original applet was developed with Visual Cafe, contrary to our standards, we don't have Cafe. So fixes are all done in text editor - java compile cycles.
I'm enclosing some code snips. The first is the method that is called to display one of the dialogs.
It loads the list, mlistSR, with our data and then makes the dialog visible. I added a this.repaint(), which didn't help, then I tried buttonSelect.repaint(), also didn't work. (At the component level, I am trying to get one component to work, if I see one and not the others, I'll know my technique works and can then apply it to all). I also tried buttonSelect.setVisible(true).
    public void showSRs(String countyCode, String townCode, RouteApplet routeApplet) {
        Vector a0 = routeApplet.routingDB.readA0(countyCode, townCode);
        Enumeration e = a0.elements();
        int r = 0;
        while (e.hasMoreElements()) {
            RASR sr = (RASR) e.nextElement();
            String id = sr.srId;
            String n = sr.srLocalName;
            mlistSR.addTextCell(r, 0, id);
            mlistSR.addTextCell(r, 1, n);
            r++;
        buttonSelect.repaint(); //this.repaint();
        setVisible(true);
    }This is our "creation" of buttonSelect:

This issue may indeed be caused by video drivers as DrClap asserts. Can it be duplicated on more that one windows 2000 box? If it cannot be duplicated, try "dumbing down" your drivers. In other words use 600x800 resolution with low color settings as a base line from which to diagnose, and find the point at which you have repaint problems.
If this issue can be duplicated, suspect the fact that you are mixing lightweight and heavyweight controls! Cay Horstman covers this topic fairly early on in "Core Java" second edition. The upshot is that the heavyweight controls will supercede the lightweight Swing controls and clause "weird" repaint behavior as the heavyweight control tries to paint on top of the Swing control.
Having worked with NetDynamices, I must congratulate you for progressing as far as you have, it was a tenuous platform in my estimation.
Good Luck in your efforts!
