Regarding the problem, reported last time, of at least some DataViz translators not working with ClarisWorks 5, Ross Willits writes: "I also had this problem until I got this work-around that completely solves the problem: Before installing CW5 (or before re-installing it) trash the Mac OS Easy Open Prefs and disable any existing MacLinkPlus control panel. Then install (or reinstall) CW5, and let it install a new MacLink Plus control panel. That done, I have had no trouble converting Word 6 files (or opening them directly from the finder with Easy Open)."
If this does not work for you (or even if it does!), you should also check out the detailed reply from DataViz on this subject. I have posted it as a new MacFixIt Extras page.
