Customer Problem Description:
---------------------------

Run SwingSet2 demo.

With sticky keys off, pressing ALT + a mnemonic does the right thing, for
example opens a menu or transfers focus.

With sticky keys on, pressing and releasing ALT, and pressing and releasing
a mnemonic does not do the right thing.

Note that there are two modes for sticky keys on Windows. One is to press
the modifier key twice, and then the mnemonic - this works sometimes. With
the other mode you only have to press the modifier key once, and then the
mnemonic - this never works under 1.3.1.

Steps to reproduce:

use the SwingSet2 demo.
  
  First goto control panel and click on Accesibility Options. Then enable 'Use
Sticky Keys'.
  
  Then bring up the swingset2 demo.
  
  When you press the Alt and F seperately, it seems to work in 1.4 but not in
1.3.1
