Windows API: ChangeClipboardChain
2003-01-31 -- Chris Thornton
That's not enough. You need to also update your m_hWndNext if you get a
wm_ChangeCBChain message from Windows. That means that the guy who you're
pointing to, just left the party and now you've got a new "next guy" to keep
track of.
Please review my developer information, particularly the "common clipboard
mistakes", and "proper implementation of clipboard viewers":

Also, if you care to test with ClipMate, I'll send you a free key. Just let
me know what you found (good or bad).
