Andreas, would you please test the attached version?
This is not the final version yet, but if it works in your
context and is fast enough, this would be fine. It's a first
proof of concept, but it shouldn't have the fix_focus problem,
and it is very fast.
As before, please replace Fl_Group::clear() with the attached
full code.

----- attached code -----
void Fl_Group::clear() {
int i,j;
savedfocus_ = 0;
resizable_ = this;
init_sizes();
// okay, now it is safe to destroy the children:
// revert them first
if (children_ > 1) {
Fl_Widget *temp;
Fl_Widget **a = (Fl_Widget**)array();
for (i=0,j=children_-1; i<children_/2; i++,j--) {
temp = a[i];
a[i] = a[j];
a[j] = temp;
}
}
while (children_) { // delete all children
Fl_Widget* o = child(children_-1); // last child widget
if (o->parent()==this) { // should always be true
if (children_>1) { // optimized removal
o->parent_ = 0; // reset child's parent
children_--; // update counter
} else { // slow removal
remove(o);
}
delete o; // delete the child
} else { // should never happen
remove(o); // remove it anyway
}
}
}
