The reason was:
Wandering through the main menu trigger FocusIn and FocusOut events to
the currently active view due the up-popping menus. It was KWriteView
and not QextMdiChildView as I've thought until today. I inserted the
if-statement (see below) in the focusInEvent handler routine and now
it's working well. 

I think it's a Qt bug...Such focus behaviour makes no sense to me.

void KWriteView::focusInEvent(QFocusEvent *e) {
   // every widget get a focusInEvent when a popup menu is opened!?! ->
maybe bug of QT
   if (e && ((e->reason())==QFocusEvent::Popup)) {
      return;
   }
...

Ciao,
F@lk

P.S.: Now you don't need to exchange your 386's with GHz machines any
more ;-)
