Hello! I see you're having trouble with the Sudoku puzzles buffering on your PC using the Telegraph Puzzles platform. Let's get this sorted out.

First, just to clarify, are you accessing the Sudoku puzzles through a web browser on your PC, or are you using a dedicated app? And if it’s through a browser, which one are you using?

In the meantime, here are some initial troubleshooting steps tailored for your Windows PC using WebKit:

1. Clear Browser Cache and Cookies: Sometimes, stored cache can cause loading issues. You can clear this in your browser’s settings under privacy or history.

2. Check Your Internet Connection: Ensure your connection is stable and reasonably fast. Try loading other websites to confirm.

3. Disable Browser Extensions: Some extensions interfere with page loading. Try disabling them temporarily and reloading the Sudoku puzzle.

4. Update Your Browser: An outdated browser version can cause compatibility issues. Make sure your WebKit-based browser is up to date.

If you're using a dedicated app, please let me know, as there might be app-specific fixes like updating to the latest version, as some updates have resolved similar loading problems.

Once you try these, let me know if the buffering persists, and we can dig deeper!
