MacSpeech has released iListen 1.0.1, which is now compatible with OS 9.2.1, when used on single processor machines. iListen is a dictating, editing, and speech navigation app. This update fixes a bug that made it impossible to run iListen on OS 9.1. According to MacSpeech;
MacSpeech is pleased to announce that based on our internal and external testing iListen 1.0.1 is compatible with Mac OS 9.2.1 when running on SINGLE processor machines.
Users of dual-processor Macs may experience some issues when performing the training exercises. The work-around is to perform training on a single processor Macintosh, back-up your user profile, and restore it to a copy of iListen installed on the dual processor Macintosh.
Some users may experience conflicts which are not directly the result of Mac OS 9.2.1 (in)compatibility. These may be specific to certain machines or the combination of extensions installed. MacSpeech is confident almost all users with single-processor Macintosh computers will be able to successfully use iListen 1.0.1 with Mac OS 9.2.1, but has not had the opportunity to test all hardware and software configurations
You can find more information about iListen 1.0.1 at the MacSpeech Web site. iListen 1.0.1 is available for US$139.00.
