Hi there! I understand that you're having trouble sending messages on Talkie because the Enter key isn't functioning as it should. Let's work through this together.

1. Check Keyboard Functionality: First, let’s check if your Enter key is working properly outside of Talkie. You can try typing in a text document or another app. Does it function normally there?

2. Restart Talkie: If the Enter key works elsewhere, try closing and reopening the Talkie application. This refresh can resolve minor glitches.

3. Check for Updates: Ensure that Talkie is updated to the latest version. Sometimes, bugs are fixed in updates. You can check for updates either in the app settings or through the Microsoft Store.

4. Disable Sticky Keys: Sometimes, Sticky Keys can interfere with keyboard operations. You can check this by going to Settings > Ease of Access > Keyboard and making sure Sticky Keys is turned off.

5. Test Different Browsers: If you’re using Talkie on a web browser, try accessing it through a different browser like Chrome or Firefox. This will help determine if the issue is browser-specific.

6. Check Internet Connection: Occasionally, a weak connection can lead to features not working properly. Ensure your internet connection is stable.

If you’ve already tried some of these steps or if anything needs further clarification, just let me know! I'm here to help you resolve this issue.
