Copy & Paste Text from other tools

I’m trying to copy a text from another tool (Word, Notepad,…) to a textarea in my Exeoutput application.
It’s just a manual operation (select text, ctrl+C, ctrl+V) but nothing works, with or without context menu.

Any suggestions?

Is it an application using Trident or Chromium engine?

Chromium engine

Any news about this?

Just wait for ExeOutput 2 with updated Chromium engine
