Hi there! I understand that while you were coloring in the Happy Color app, it suddenly started zooming in and out on its own, and now you can't color properly. Let's get this sorted for you.

Just to clarify a couple of things first:
- Are you using Happy Color on a browser (WebKit on Windows 10), or do you have it installed as an app on your device?
- Does the zooming happen randomly, or only when you try to color or touch certain areas?
- Have you tried anything so far to stop the zooming?

In the meantime, here are some steps you can try to troubleshoot:

1. Check Touch or Mouse Inputs
Since you mentioned it's zooming in and out, sometimes "touch alternatives" or certain zoom gestures can be triggered accidentally. If you're using a touchpad or touchscreen, try disabling pinch-to-zoom gestures temporarily or be cautious with multi-touch input.

2. Hold Down Modifier Keys
One workaround reported by users is to hold down the Option (Alt) key while coloring to manually control zoom functions, which might help prevent the app from zooming erratically.

3. Refresh or Restart
If you're in a browser, try refreshing the page. Also, close the browser completely and reopen it, then reload Happy Color. Sometimes temporary glitches cause zoom behavior.

4. Clear Browser Cache and Cookies
Sometimes stored data can interfere with app behavior. Go to your browser settings and clear the cache and cookies for the site, then reload the app.

5. Try Another Browser or Update
Since you are on WebKit on Windows, make sure your browser is up to date. Alternatively, try accessing Happy Color on a different browser to check if the issue persists.

6. Disable Browser Extensions
Sometimes browser extensions interfere with web apps. Try disabling extensions temporarily and see if that stops zooming.

If after these steps the issue continues, it might be related to a bug or settings within the app itself. Let me know the details I asked about and what you've tried, and I can guide you further!

Are you satisfied with this initial guidance, or would you like me to help further?

I'm using memu 9 and I didn't face this problem before and I don't know the proper solution

Thanks for letting me know you're using MEmu 9! That's an Android emulator, so the zooming issue might be related to how MEmu interprets your input or graphics handling for the Happy Color app.

Let's try some targeted steps to fix this:

1. Check MEmu's key mapping and input settings:
Sometimes the emulator’s multi-touch or zoom gestures get triggered by mouse or keyboard inputs. In MEmu, open the Key Mapping settings and disable or adjust any zoom or multi-touch gestures to avoid accidental zoom in/out behavior.

2. Update MEmu and Graphics Driver Settings:
Make sure your MEmu emulator is updated to the latest version. Also, check MEmu’s graphics settings—switch between OpenGL and DirectX rendering modes to see which one works better for Happy Color. Some games or apps have glitches with certain render modes causing zoom or graphical issues4.

3. Clear Happy Color app cache and data within MEmu:
Go to MEmu’s Android settings > Apps > Happy Color > Storage, then clear the cache and data. Restart the app and see if the problem persists. Sometimes cached data causes unexpected behavior.

4. Reinstall Happy Color app:
If clearing cache doesn’t help, try uninstalling and reinstalling Happy Color inside MEmu. This refreshes the app and might resolve bugs that appeared due to corrupted files1.

5. Adjust Emulator screen resolution/scaling:
Sometimes scaling or resolution settings in MEmu cause awkward zoom effects. Try adjusting your emulator's resolution or DPI from settings and test if zooming stops.

If these steps don't resolve the zooming problem, please tell me if it happens only in Happy Color or if other apps in MEmu show similar behavior. That will help narrow down whether it’s an app-specific issue or emulator-wide.

Would you like me to walk you through any of these steps? Are you comfortable accessing MEmu’s settings? Let me know how I can assist you best!
