Not-so-test case

(09:34:33 AM) zezula: well, all error codes are generated by the same code:

// Open the archive
            if(!SFileOpenArchive(szMpqName, 0, dwFlags, &hMpq))
            {
                nError = MessageBoxError(hWorkerDlg, IDS_E_CANT_OPEN_MPQ,
GetLastError(), szMpqName);
                break;
            }

The author was kind enough to write a testcase, unfortunately it didn't display
that behaviour. Still, here is the code and exe if anyone is interested and
feels like using it to try and reproduce the issue.

Note that only some error messages appear under the active window; eg opening a
folder or non-existing file. Opening a bad-format file doesn't generate an
error.
