Calendar days view incorrect

Any idea why the calendar seems to word wrap or something and the weekdays appear wrong?

Hi,

It looks like a CSS issue, does it happen with other themes?

Cheers,

I'll check with another theme, not sure.

One thing that seems to have an effect on it is:

th:first-child, td:first-child{
padding-left: 5%;
}

style.css : 620
Reducing the padding-left to 2% or less seems to fix the problem, on my screen anyway.
