Hi Angela Sigee  ,

I get this Object reference not set to an instance of an object error when I open a TXT file in Trados Studio and hover the mouse in any column of the Editor (segment #, Source, Status, Target or DSI).

XML attached with error details:

As you can see, Wordbird might be causing the issue. If I uninstall Wordbird, the error is gone.

Notes:

• It doesn’t matter how I added the TXT file, whether via Translate as single document or to and existing project, the error shows up.
• As mentioned before, no need to click on the segments to trigger the error. Just hovering the mouse will do it.
• DOCX, XLSX, XLF files seems to be fine. Only TXT ones have the issue. The TXT has the default settings created by Windows OS. I attach a sample TXT file anyway:

Maybe you could have a look at your app? Thanks!
