If you look at the conditions under which it is called(NULL rectangle and no WRITEONLY lock or something like that), you'll quickly see that the hack will break as soon as the application behaves differently, e.g. passes a rectangle that is bigger than its window but not NULL, or specifies WRITEONLY(pointless flag), etc. Furthermore the behavior this hack gets working is broken on Vista, so it is only a matter of time until the applications are fixed or obsolete.
