WinXP(or 98), upp 511 MinGW bundled, Analog clock hello world example. Build it, execute it. Everything OK. And then press the [down] key on your keyboard. It cause a memory error of the clock example.

Or try AnimatedHello or Color example. Or probably any other UPP program with main frame without child windows (buttons, menu, ...).

bool TopWindow::Key(dword key, int count)
{
if(Ctrl::Key(key, count))
return true;
if(IsChild()) return false;
if(key == K_DOWN || key == K_RIGHT || key == K_TAB) {
Ctrl *ctrl = GetFocusChildDeep();
if(ctrl && IterateFocusForward(ctrl, this))
return true;
if(GetFirstChild()->SetWantFocus())

BUG BUG BUG GetFirstChild() probably return NULL

Indeed!

Thank you. It is amazing for how long this went unnoticed (there is not too many childless windows in real programming I guess...)

Fixed.
