After yesterday’s abortive release of Eudora 4.3, Qualcomm has quickly uploaded version 4.3.1, which fixes a bug caused by a single line of code being inadvertently removed in the final compile. The bug? In Sponsored mode, Eudora 4.3 wouldn’t fetch ads. Unfortunately, Eudora 4.3 will get cranky and start nagging after not receiving ads for several days and will automatically switch down to Light mode after a few weeks. So if you downloaded 4.3 and are using it in Sponsored mode, you’ll want to get 4.3.1 instead. Again, if you’re a current Eudora Pro 4.x user, wait for the updater that will bring you up to Eudora 4.3 and register you in Paid mode, due later this week – the full Eudora 4.3.1 won’t accept Eudora 4.x registration numbers.
Also note that we biffed the system requirements for Eudora slightly in this week’s article in TidBITS 517. Eudora 4.3.1 requires a PowerPC-based Mac with Mac OS 7.6 or above with QuickTime 3.0.2 or later (which you can download from the custom installation screen in Eudora’s installer). Eudora 4.3.1 is a 5.6 MB download.
