This issue is corrected in 1.0v3.
ClarisWorks is not compatible with Thunder 7, an interactive spelling checker from Baseline Publishing. In order to improve performance, ClarisWorks takes key entry at a lower level than Thunder. The result is that ClarisWorks is faster than Thunder and not all of the characters typed into ClarisWorks are read by it. Since Thunder receives incomplete words, it beeps as if you had entered an incorrect spelling.
