DL  What's to consider? Fundamentally, no other direct document integration options exist. It's all we've got to work with. The Text Services Manager (Input Menu) integrates text correction utilities into a host application much as Microsoft Word integrates its spelling and grammar checking. Grammarian's universal design concept is to integrate into ALL applications from the menu bar. Therefore, you have a grammar and spelling checker, dictionary, and AutoCorrect in Mellel or Apple's Pages much as you have in Microsoft Word. If you don't like Apple's ancient TSM Input Menu design, write to them: http://www.apple.com/feedback/mac/tm.html

DL  This is rather harsh. Pardon me for not seeing this earlier. I've never seen or heard of this happening to ANYONE before. And, I've never received any notification from you about this either. Anyhow, this sounds like a rare Grammarian.component file corruption or file copying issue (permissions?).

Write to Apple about another means for text/writing utilities to grab keystrokes. The input menu is the only means that Apple gave developers to do this. I begged Apple engineers at WWDC back in 2000 for a better OSX solution. This is it because of OS security. Don't blame Grammarian for this design issue. Other input menu developers (Typeit4me, etc.) have the same problems.

DL  Sorry for not seeing this until now, but I don't get around the review sites looking for people who need tech support. The answer for this was posted on our site. Our serial server was down momentarily because of International Internet Guild changes (com/net/org). Our .org domain timed out until the Guild made their changes. Anyhow, I posted a followup with a simple solution: Momentarily disconnect your internet connection. Again, this issue was resolved long ago when the Internet Guild came back online for .org domains. New versions of Grammarian allow for this type of (future) issue.
