Well here's one for you ....... the clock display is corrupted today on boot up!
Although I don't need it there I left it in place last night when I shut down.
I had done multiple reboots yesterday with it in place ..... trying out different kernels ..... and it never corrupted.
Today all I see are three 'strokes' (7pm, 9pm, 11pm) and a flickering where the second hand should be. Yes I had added the second hand display before I finished last night when I was timing an app launch in a kernel.
Clicking on the 'resize' box, without actually resizing the widget, gave me the correct display again.
So it seems that all is not well here either.
I will leave it in place for a few more days, without second hand, to see if anything else happens.
