Hello,
Sorry to hear you are having issues. Need to know more on your system.
- Windows version, please use Windows Winver.exe for full Windows version numbers.
- Tiles version.
- How did you move it? Click and drag on Tiles Config Windows->Pages? or Click and Drag on Tiles pages itself?
- When you said it gray out, did you click on the "Tick" next to the page name and make it active again?

Thanks
