Question about win32 beta

[ClassOneSW at aol dot com]

Sorry if this question is common knowledge, but I just joined the betas list because I am interested in the pending (?) release of RB for Windows. I have tried to transfer my Mac projects to the Windows b5 version. RB does not recognize the project as a RB file. When I choose to "show all files" it will open the project, but then crashes with a "invalid page fault" error.
Now the question: Is it anticipated that in the final release of RB for Windows that one will be able to transfer Mac projects to win? If not, this will severely limit the usefulness of RB for Windows (at least for me)

TIA
