Hi! I see you’re having trouble with copying in your MT app. Just to clarify and better assist you, could you tell me more about where exactly the copy action is not working? For example, is it within the MT app project itself while working in the app builder, or is it when trying to copy text or components during use? Also, are you experiencing this on your Windows 10 device with WebKit browser, or somewhere else?

Meanwhile, I can share some general steps that often help resolve copy issues in apps like MT:

1. Restart your device: A simple reboot of your Windows 10 system can clear temporary glitches affecting clipboard functions.
2. Update the MT app or platform: If you are using the MIT app inventor or similar, make sure you’re working on the latest version from the official code.appinventor.mit.edu server, as some copy-paste bugs have been fixed there recently.
3. Check clipboard history and permissions: On Windows, clipboard history can be toggled on or off in settings. Also, confirm that the MT app or browser has necessary permissions to access the clipboard.
4. Clear clipboard contents: Sometimes, clearing the clipboard cache helps. You can do this by copying a small piece of text or using Windows’ clipboard clearing utilities.
5. Try a different browser or open your project in an incognito/private window to rule out browser extension conflicts.

If copy-paste still doesn't work after these steps, please share more details about your usage context. That will help me guide you to a more specific fix or escalate if needed.

Are you satisfied with these initial suggestions so far?
