Some never learn

I downloaded the Dragon Age II PC demo, to find that mouse wheel support is broken - a familiar tale. (Specifically, support for freely rotating mouse wheels with non-120-multiple wheel rotation values). Ho-hum.

Careful with SHAutoComplete

If you call it with a NULL HWND, it will return E_INVALIDARG but leak six GDI handles (seen under Windows 7 SP1).

Yes, you can blame the caller, but 'tis just something to note.
