On windows, Robot.keyPress(KeyEvent.VK_RIGHT) always types NumPad right arrow key regardless of the NumLock on or off. There is no way to force the Robot to  to press the non-numpad arrow key.

Tested with jdk 1.4.2 b18.

Steps to reproduce:

1. Compile altkey.java attached below.
2. run using 'java altkey auto'
3. Robot always presses numpad right arrow key.
4. Some character is typed in the textfield.

5. run using 'java altkey man'
6. Press Alt+Right (non-numpad key) and release in the textfield.
7. No character will be typed in the testfield.
