For this piece, I use one call:
SHFullScreen( m_hwn, SHFS_HIDETASKBAR | SHFS_HIDESIPBUTTON |
SHFS_HIDESTARTICON )

I'm surprised separate calls (such as your method) work, and hope
someone else will clarify.

I concur with the earlier post that suggests handling WM_ACTIVATE
messages. I certainly seems to work for me, although I haven't done
extensive testing.
