W10 Taskbar clock is Black and won't open calendar when clicked.

[wayward95]

Hi all,

Despite having exactly the same Open Shell versions and settings at work as on my home PC, at home the clock is Black rather than white and when I click on it the calendar does not appear, just the loading circle for a couple of seconds.

I've tried lots of the W10 discussion forums and none of the solutions work.

Does anyone have any suggestions please?
Thanks!!
Dave
