Bug ID: 36753
           Summary: UltraISO can't open image with a lot of files
           Product: Wine
           Version: 1.7.20
          Hardware: x86
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

          Reporter: [e-mail]

UltraISO can't open .dmg or .cdr with about 23,000 files. Both images open fine
on my mac.
When program starts, wine shows about 10:
fixme:win:LockWindowUpdate (0x10020), partial stub!
fixme:win:LockWindowUpdate (0x0), partial stub!
and one at the end:
fixme:ntdll:server_ioctl_file Unsupported ioctl 24000 (device=2 access=1 func=0
method=0)

Console doesn't show any new errors when opening fails, UltraISO, however,
shows a window with an error(see screenshot).

I tried opening other images, with UltraISO, they open fine.

UltraISO version is 9.6.1.3016
