Hi! I understand you're having trouble closing the gift card overlay on the Funky Pigeon app on your Windows device using WebKit. I'd like to help you get this fixed.

Just to clarify first—are you using the Funky Pigeon app downloaded from the Microsoft Store, or are you accessing Funky Pigeon via a web browser on your Windows 10 machine? Also, when you say "cannot shut down the gift card overlay," does that mean clicking outside the overlay, hitting a close (X) button, or pressing escape doesn't do anything?

Knowing this will help me guide you better. Meanwhile, here are some general first steps you can try:

1. Try Clicking the Close Button: If there’s a small "X" in a corner of the overlay, give that a click carefully.
2. Click Outside the Overlay: Sometimes clicking outside the overlay window should close it.
3. Press ESC Key: Press the ESC button on your keyboard to close any popup or modal overlays.
4. Refresh the Page: If you are on the web browser, refreshing the page can sometimes clear stuck overlays.
5. Clear Browser Cache: Since you mentioned WebKit, clearing the browser cache can help eliminate interference from stored files.

Let me know if any of these moves the overlay, or share more details on exactly what happens when trying to close it, and we can go from there.
