In TreeCtrlDnd there is also a critical bug. If you select all rows in the left panel and drag them to the right side, and then you will try to drag them back application will crash.

Try to change column width 
|
Fixed...

Indeed it's better! but I found another crash. However it's hareder to repeat. What I do is:
1 Set column width to minimum
2 Choose one item and start draging it over the window back and forth, up and down until the crash.

Crash is here
void Ctrl::WndFree()
{
if(!top) return;
RevokeDragDrop(GetHWND());
ReleaseUDropTarget(top->dndtgt);
isopen = false;
HWND owner = GetWindow(top->hwnd, GW_OWNER);// CXL 31.10.2003 z DoRemove
bool focus = ::GetFocus() == top->hwnd;
LLOG("Ctrl::WndDestroy owner " << (void *)owner
<< " focus " << focus
<< " ::GetFocus() " << (void *)::GetFocus());
if(owner && focus)// CXL 7.11.2003 presun - melo by to fungovat take a neblikat...
::SetFocus(owner);
LLOG(EndIndent << "//Ctrl::WndFree() in " <<UPP::Name(this));
delete top;
top = NULL;
}
in line
HWND owner = GetWindow(top->hwnd, GW_OWNER);// CXL 31.10.2003 z DoRemove
I found better way to repeat the crash.
1. chagne column width until value 382 is in last column (see attached picture)
2. Start dragging value 382 to the left.
