And the reason this happens is something like:
SetFocus on the edit window triggers a KILLFOCUS message to the treeview.
KillFocus triggers an update window on the treeview, which calls TREEVIEW_Refresh.
TREEVIEW_Refresh calls UpdateScrollBars, which is the function I modified.
With my mod, if there is a horizontal scrollbar, then TREEVIEW_HScroll is called.
Very near the top of TREEVIEW_HScroll() is:
    if (infoPtr->hwndEdit)
    SetFocus(infoPtr->hwnd); 
So that removes the focus from the edit window, and returns it to the treeview.
The simple fix is to comment out those two lines.

I guess if the user moves the scrollbars, maybe the focus should be changed. But
probably only on a click on the scrollbars (I guess some testing on Windows is
needed).
