Hi Sharon. This is actually a reported issue that is currently under investigation that has to do with the real-time spell checker in the text boxes. Unfortunately, there is not a way to turn this off. One thing you can do is delete your local temp files - this will get rid of built-up temp dictionary files that may help a little. Additional workarounds are in KB article 106528.

This issue is with report forms and all notes in report writer. If you have a copy of the old Sage  (2014), you can create your report form in 2014 and when done move it over to your current version. I found this to be the only saving grace, as I was doing an 18 page subcontract form. Hope this helps.
