Hi there! I understand that the "Last Refresh" window is blocking your ability to scroll down in the London Bus Times Countdown App on your Windows device using WebKit. That sounds like a tricky situation to work around.

To help resolve this, could you please let me know if this "Last Refresh" window stays on the screen permanently, or does it appear only after refreshing the bus times? Also, have you tried clicking anywhere on that window or tapping a close or dismiss button? Sometimes it might be a pop-up that can be closed manually.

In the meantime, here are some steps you can try to remove or bypass that window:

1. Refresh the Page/App:
- Try refreshing the bus times within the app or browser tab. Sometimes the "Last Refresh" display automatically disappears a few seconds after it updates.

2. Scroll After Delay:
- Wait a few moments after the refresh to see if it automatically clears. Some overlays show briefly to indicate data update.

3. Clear Cache and Cookies:
- Since you are on Windows with a WebKit browser, clearing the browser cache might help if the app is web-based. This clears any stuck interface elements.
- Steps: Go to your browser settings > Privacy or History > Clear browsing data > Cache and cookies > Clear now.
- Then reload the app.

4. Zoom Out or Resize Window:
- Try zooming out the page (Ctrl + Minus) or resizing the window. This sometimes shifts the interface so blocked elements become accessible.

5. Check for App Updates:
- If you are using a desktop app version, check for updates. The problem might be fixed in the latest version.

6. Try a Different Browser:
- Switching to another browser temporarily (e.g., Chrome or Firefox) might show if the problem is browser-specific.

If these steps don’t help, we can go deeper by checking if any settings inside the app control the "Last Refresh" display, or if it's a glitch that needs developer attention.

Please let me know what you have tried already and any other details about when exactly this window appears. That way, I can guide you more precisely! Are you able to interact in any way with the "Last Refresh" window right now?
