You don't have any problems on processing keyboard events? I have an
application that uses keyboard and I think that my application processes two
events instead of one? Have this happened to you? Do you have any idea about
this? Maybe it's code error that I still haven't found. I'm working on that,
but seeing that you were working on keyboard events, I didn't resist putting
the question.
