Hekko Susanna R Miles ,

If this was a general issue, we would see many more cases- so I think at this stage this must be a local issue.

Could you please provide the actual version number of MultiTerm that you have installed please.

Also, please try resetting windows layout in both Studio and MultiTerm- reboot your machine and restart Studio.

Did this help?

Thank you Steven,

I had done all of the above and none of that worked. 

I did set up a new (test) project and in that it worked, so apparently it just didn't like the update "mid-project" as far as still being able to add a corrected term to MultiTerm - which is OK. I corrected it in the standalone version. - 

I meant to withdraw the question after the test worked, but got busy and forgot. 

Thank you for your time, 

Sincerely,
Susanna
