It's possible to deselect the subcommands of option one when i select option two?

I hope the following change (RED) in listviewex.c could solve the problem. I have used sourcecode 2.1.9.3:

...
int ListViewExSetCheckState(HWND hLv, LV_EX_ITEM* Item, LV_EX_STATE State) {
LV_EX_ITEM *Parent, *Child;
Parent = ListViewExGetParent(hLv, Item);
if (Parent && Parent->Flags & LVEXF_GROUP) {
Child = Parent->Next;
while (Child) {
if (Child->Indent <= Parent->Indent) break;
if (Child->Indent == Item->Indent) {
Child->CheckState = 0;
Child = Child->Next;
if (Child->Prev != Item){
while (Child && Child->Indent > Item->Indent) {
Child->CheckState = 0;
Child = Child->Next;
}
}
}
else
Child = Child->Next;
}
}
Item->CheckState = State;
return 1;
}
...

CU, opensurf

No it isn't as easy as you think. And also it isn't wanted.
Take this example:

(x) Option 1
    [x] Sub Item 1
    [ ] Sub Item 2
    ...
( ) Option 2
( ) Option 3

May be you decided to unselect "Sub Item 2". "Sub Item 2" could have hundreds more items which you manual selected. If you then select "Option 2" entire work selecting subitems from "Option 1" is in vain. This is mostly unwanted!
