Bug #: 33999
           Summary: IncrediMail crashes on startup (GetNextDlgTabItem
                    shouldn't return NULL?)
           Product: Wine
           Version: 1.6-rc4
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: user32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

After working around bug 33996 with 'winetricks wsh56vb vcrun2005',
and bug 33998 with 'winetricks ie7', it eventually finishes its very
long 'configuring' progress bar.  The next dialog crashes when you click
'next',
with:

Unhandled exception: page fault on read access to 0x00000020 in 32-bit code
(0x25ff6766).

And applying the patch
http://marc.info/?l=wine-patches&m=127045782322161&q=raw
"user32/dialog.c: GetNextDlgTabItem returns hwndDlg if next item not found"
by Mikhail Maroukhine works around the problem.
