Why any applet doesnt start in IE4.0 (NT4.0), until I click in the applet area. In netscape all its ok. In the Init method of the applet I call requestFocus() and repaint.
Thanks.

maybe you should show the source here, or give a link to the applet.

ok. the link of my applet is http://members.xoom.com/lakes/Ilustr.html
but
public class Thing extends Applet
{
 public void init()
 {
  requestFocus();
  repaint();
 }
 public void paint(Graphics g)
 {
  g.drawString("I wont appear until click",10,10);
 }
}
wont display anything until I click in the applet area. This only happens in IE4.0(NT), not in Netscape(Mac/PC) and in IE3.0(Mac).
Why?

I have a NT 4.0 and IE 4.0 . I ran the above applet and it worked perfectly fine. I did not have to click in the applet to get it working. repaint() tells the system that the applet needs to be redrawn. The browser responds by invoking the paint method of the applet the next time it has a moment , which is usually right away (but necessarily) . This means that if the browser is busy doing something else the paint method call could be delayed.

I had the same problem. repaint() doesn't seem to call the update function in IE4 (don't ask me why). However, I solved my problem by forcing the call to update().

Here's the protion of code I used:

init()
{
appletImg = createImage(maxWidth, maxHeight);
appletG = appletImg.getGraphics();
this.repaint();
update(appletG);
}
public void update(Graphics g)
{
paint(g);
}

My applet seems to run well, when I update to Internet Explorer 4.x
