Thank you for your thoughtful reply. I tried exactly what you wrote, saving the entries in both WP as well as MSWord.
Since my previous note, I have realized that it only happens when I insert the text in WP when the document is fully justified, which all of mine are.
I am not using the glossaries that came with Instant Text, but I also did a search and S1 did not come up, so that is not the problem. The problem also occurs with other formatted items such as Streptococus (in italics)......
Thank you again for your reply....any other thoughts?
