Hello Gerald Clerge,
Welcome to the Microsoft Community.
Thank you for your feedback. Based on your description, you are unable to copy and paste in Copilot. Could you please clarify if you are unable to paste text into Copilot's input box, if you encounter an error when pasting images, or if you cannot copy Copilot's responses? Providing more details or screenshots of any errors will help me better understand your issue.
If you are unable to paste text into Copilot, try selecting the text, copying it, and then using the shortcut Ctrl + Shift + V to paste as plain text into Copilot.
If you are having trouble pasting images, try reopening a new Copilot chat window and attempting again, or use the upload button in Copilot to attach files. Alternatively, you can use the screenshot tool in Edge to capture and paste the image.

I hope this information helps. If you have any further questions or need additional assistance, please feel free to reply. I am happy to continue helping you.Thank you for visiting the Microsoft Community. Wishing you good health and a pleasant life!
Best wishes,
Amos.L - MSFT | Microsoft Community Support Specialist
