Hi,

I tried to debug our plugin on Trados2021. Then i got following exception during debug session.

According to exception message, _noFilesLabel is updated by other thread. 

I checked our plugin and our plugin doesn't have _noFilesLabel  control. I think that FileDetailsViewPartControl has this control and it updated incorrectly.

Is it bug of Trados?

Is there any workarounds to prevent exception from trados controls ?
