After you have done a spell check in ClarisWorks 5.0 using Spell Catcher from Casady & Greene you will be returned to your ClarisWorks document and the spelling changes will be accomplished if any errors were detected; however, you will notice that your cursor is gone and clicking into the document does not display the cursor.
Solution:
To refresh the screen so that the cursor reappears and you can select words by clicking your mouse you need to switch to the finder or another running application and then back to your ClarisWorks document to get normal control over your document.
