An AppleWorks 6.2.4 updater is out. Among the minor changes listed is "the ability to read and write Microsoft Word and Excel files," a confusing phrase since this feature is not actually new. However, it does now properly open Office files when they are double-clicked in the Finder, which wasn't the case for me before (despite their having been identified as AppleWorks-owned documents). It also launches much faster than 6.2.2 did for me.
