Hi there! I understand that when you click on the boxes in the Blocks Classic app, nothing happens, correct? Just to get a better idea, is the app freezing entirely, or is it just that the clicks on the boxes don’t get registered? Also, are you using the app on your Windows 10 device through a browser or as a standalone app?

Meanwhile, here are some general steps we can start with to troubleshoot:

1. Restart the app: Completely close the Blocks Classic app or browser tab you are using, and then open it again. Sometimes, a fresh start clears temporary glitches.

2. Clear cache and cookies: Since you’re on Windows 10 using WebKit-based browser, clearing cache helps eliminate corrupted temporary files that might block interaction. You can do this via browser settings.

3. Check for updates: Ensure your browser is up to date. An outdated version can cause compatibility issues with interactive web apps like Blocks Classic.

4. Disable browser extensions: Sometimes browser add-ons interfere with app functions. Try disabling extensions temporarily to rule that out.

5. Try a different browser: If possible, open the app in another WebKit browser or a non-WebKit browser like Firefox or Edge, to see if your current browser is the issue.

6. Restart your device: This helps resolve background conflicts or resource locking that may impact app responsiveness.

If these don’t help, can you tell me if this happens with all puzzles or just specific ones? Also, does it happen every time or intermittently?

Let me know what you observe, and we can dig deeper!
