Isn't it odd...

I recently had my first run-in with a Microsoft docx document. A friend was complaining tht she couldn't open it with the version of Microsoft Word that she runs. She was told to download a conversion program, but both times she did that, her computer crashed. I tried opening the document with OpenOffice 2.4 and had no problems with it at all. She was amazed. I said, "Of course!"
