Error: SelectedTab cannot be set before the pane has been added to a panes collection

Hi,

Each time I want to open a new document or a previously translated project, the error message appears: SelectedTab cannot be set before the pane has been added to a panes collection. (2 same messages).

I use Trados 2019 with Windows 10Pro

I have tried Reset Window Layout and SDL Freshstart.

I also reinstalled Trados, but no success.

Does anyone know how to fix it?

Regards,

Krzysztof

  • what did you do in freshstart? What version of Studio are you using?  Make sure you have this one:

    SDL Trados Studio 2019 SR2 - 15.2.7.2849
    SDL MultiTerm 2019 - 15.0.6.56482

    Then do…
