This is true only for nt family windows. :-P
On 9x test function exits on an exception.

I don't understand much in all this OLE/In-Place stuph, so I agree, but 
still I doubt this would be a sufficient to proof my patch is correct.

I will try, but what should be done with this (inside test_HTMLDocument)?

|         OLECMD cmd[2] = {
|             {OLECMDID_OPEN, 0xf0f0},
|             {OLECMDID_GETPRINTTEMPLATE+1, 0xf0f0}
|         };
| 
|         hres = IOleCommandTarget_QueryStatus(cmdtrg, NULL, 2, cmd, NULL);
|         ok(hres == OLECMDERR_E_NOTSUPPORTED,
|                 "QueryStatus failed: %08lx, expected OLECMDERR_E_NOTSUPPORTED\n", hres);

Or IOW, why first call generates exception on OLECMDID_OPEN command while 
second do not?

|         hres = IOleCommandTarget_QueryStatus(cmdtrg, NULL, 2, cmd, NULL);
|         hres = IOleCommandTarget_QueryStatus(cmdtrg, &IID_IHTMLDocument2, 2, cmd, NULL);

OLECMDID_OPEN seems to be supported at least on winME.  I am curious, why?

What do you exactly mean by "it"?

No, the patch didn't help.
