If I want to use something in the concordance, if I click in the segment to select, copy, and paste: as soon as I first click, instead of letting me work, I have to click OK on the error message that comes up and then click on the concordance tab, scroll to where I was, and then select, copy, and paste. I've tried clicking on the scroll bar first instead of directly in the segment, and sometimes it would work. But lately it doesn't matter where I click; I still get the annoying error message.
The error says: Object reference not set to an instance of an object.
There is good knowledge base for this issue. Please see the link below:
