It would be nice if statistiXL was supported on all platforms MS Excel is, i.e. Macintosh as well. There still are a few of us who prefer the Macintosh plug-and-play to the Windows plug-and-pray. I don't know how cross-platform compatibility for Excel add-ons is, but perhaps it is as easy as designing an installer that works with Macintosh as well, e.g. with Installer VISE from MindVision Software. If not it could be a good idea to at least state clearly which platforms statistiXL is and is not supported on.
