Hello,
Sorry to hear you are having issues. Need to know more.
1) Installed Windowblinds version.
2) Installed Start10 version.
3) Windows 10 version. Please use Winver.exe for full version numbers.
4) Is this happen on all windowblinds theme start buttons or specific start button or Windowblinds theme?
Thanks
