New OPEN OFFICE - beta for Win, MAC and Linux

Worked fine on my MAC. No hitches, whatsoever. -tp.

Here is what the FEATURES page said about the Windows version:
In addition to read and write support for the Microsoft Office binary file formats (.doc; .xls, .ppt, etc.), OpenOffice.org 3.0 is now capable of opening files created with Microsoft Office 2007 or Microsoft Office 2008 for Mac OS X (.docx, .xlsx, .pptx, etc.).

Thus, OpenOffice.org users can interact with users still using Microsoft Office. The various filters for the Microsoft Office file formats also make mixed environments possible, so that some users stay on Microsoft Office while others use OpenOffice.org.
