When main frame has no notebook component then error exist:
- on Windows Vista, ghc 6.10.3, wxhaskell-0.11.1.2 - "Failed to load shared library 'comctl32.dll' (error 126...)" (after closing error window the application works correctly)
- on Windows XP, ghc 6.10.2, wxhaskell-0.11.1.2 - "Segmentation fault" and application is broken (the same message like in bug 2599836)
when notebook (invisible!) component is created then all is OK.
