Hi Anthony Rudd,

If repairing and the other you tried don't work, have you also tried to reset?

Does it work now?

Regards,

Thanks, the Reset worked. Although I am surprised, because I have done it several times recently without any effect. Perhaps it was only in combination with the other two measures.  

Unfortunately the fix did not last long - the error has returned.

Sorry to hear this Anthony Rudd,

Do you remember specific actions, or maybe put the PC to sleep or even having 2 instances opened of it, small details to help us understand this behaviour? Can you please check in your Task Manager if you have more than 1 instance running, maybe force it to close even that one, and open it again.

Regards,

Unfortunately the problem has returned again with no obvious cause. Perhaps a solution would be for Trados Studio to be "less fussy" when checking the settings associated with the "Restore" button.  

Did you try to turn off the Tablet Mode (All Settings, System, Tablet [Mode])? 

I hope this is not a stupid question, but where do I make this setting? Studio 2019

This is a Windows 10 setting and  a Windows 10 issue. I don’t think Trados has anything to do with it. But I may be wrong. Just try.

Thanks, my mistake. I have changed the setting and will see whether it has any effect.

Hi Stepan. Unfortunately, this setting did not help - the error has returned today.
