You're welcome. In U++ it is fairly common to use a static variable in global function instead of global variables to prevent all kinds of troubles that global variables cause.
In your case, you can do something like
KeyBuddy2* MainWindow() {
static KeyBuddy2* ptr;
return ptr;
}
...
KeyBuddy2::KeyBuddy2()
{
MainWindow()=this;
CtrlLayout(*this, "Window title");
SetHook();
}
...
MainWindow()->ProcessKbdEvent(...)
There is even a macro for this: GLOBAL_VAR(type, name), for those that are too lazy to write  (Such as me  )
