FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)


FULL OPERATING SYSTEM VERSION :

Windows 98 [Version 4.10.2222]

A DESCRIPTION OF THE PROBLEM :
Applets receive the F1 key events but the Microsoft Internet
Explorer Help panel ALSO pops up, even though the applet
calls the "consume()" method to prevent the key from being
processed by the browser.

This anamalous (and annoying) behavior occurs ONLY when the
applet is run under the Java 2 Plug-in in the Microsoft
Internet Explorer browser. When the applet is run under the
Java 2 Plug-in in the Netscape 6.2 browser, it works
correctly. It also works correctly when run under
Microsoft's own Java 1.1 support in Internet Explorer. Also
works correctly in Netscape Navigator 4.x browsers with
Netscape's version of Java 1.1.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Code a Java applet and Web page that handles function
keys F1 through F12 and logs them in the Java Console window
(see sample applet below).

2. Install the applet and Web page on a Web server.

3. Use a browser to access the Web page with the test
applet. Be sure the Java Console is activated.

4. If using my sample applet, press function keys F1 through
F12. The applet will log these keys with messages
in the Java Console. F1 (and ONLY F1) will cause the
Microsoft Internet Explorer Help window to "pop-up".

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED:

Only the applet processes the function keys.

ACTUAL:

The applet receives the event call for KeyEvent.VK_F1 and
the applet calls "consume()". But the Microsoft Internet
Explorer Help window "pops-up" anyway!

This bug can be reproduced always.
