My problem is my derived class is getting called twice instead of the

I want my base class to have its method called and then the derived
class have its method called. What am I not understanding?

Int the following code, my Event Tester class is getting called twice
for keyboard events when I step through the debugger:

You couldn't have posted in worse shape, even if you tried, probably.

I couldn't make heads or tails of the code, I am sorry. Why do you
use 'dynamic_cast' to the same type from 'this'?

Anyway, if you think you're having a language problem (which I am not
sure you do, however), remove unnecessary code and make sure you have
read and follow the recommendations in FAQ 5.8. Most likely you have
some kind of logic problem, but with the code you posted it was not
possible to assertain without spending too much time trying to get it
back in shape.
