Note: Due to bug #4186905 text components don't forward key-typed events
in JDK 1.2 for Win32.

This bug was integrated in 1.2.2. Perhaps it would be okay to remove the
note from the Tutorial now. I tested the testcase submitted with 4186905
with 1.4 on both windows and solaris, and it worked fine in both cases.
