[Lazarus] usability: please not focus the messages window, only bring to front

[Bernd]

Does anybody know where is the code located that is executing when I
compile something and that is writing the messages to the messages
window? I only need some starting point so I can try to step throuhg
it but the codebase is so uge that I just can't find it.

On compilation when there occurs an error it is definitely trying to
focus the message window, exactly at the moment the error occurs. My
window manager does definitely NOT focus things on its own, something
must call setfocus but I can't find it.
