I'll guess you're not the same person? https://github.com/White-Tiger/T-Clock/issues/54

Sorry, but I didn't notice that report.
I'm a different person.

For me, it doesn't necessarily happen right after I log on..
I rather suspect that T-Clock doesn't refresh itself properly when the date changes, but I'm not sure.

is it the primary or secondary clock?

-WhiteTigX (August 13, 2016, 08:05 AM)

I've only got one monitor.

Horizontal or Vertical taskbar?

-WhiteTigX (August 13, 2016, 08:05 AM)

Horizontal

Is the clock size larger or less than the Windows clock size?

-WhiteTigX (August 13, 2016, 08:05 AM)

Larger (Arial / 11 / Bold).
These are the same settings that I used with build 151, where the problem never occured.

What means "sometimes"?

-WhiteTigX (August 13, 2016, 08:05 AM)

Since I installed build 419 eight days ago, I've noticed it 3 or 4 times.

EDIT:
After messing around with it a bit now, I've figured out where the problem lies..
T-Clock doesn't refresh itself properly when the taskbar is hidden (which mine usually is).

are you sure you're running the latest version? (Beta2, build 419)

I can confirm that the issue is fixed in build 419.
Good work! :)
