[Lazarus] An expression is returning false, why?

[Lubos Pintes]

Hello and thank. And in general, if I have a TControl instance, can you 
tell me a reliable algorithm that tells me if the control has a focus? 
Only if it makes sense of course. So probably something like I tried 
before, that is the control is a TWinControl instance and the Focused 
property is true?
I know it doesn't work for a form itself. Maybe this is a bug?
