Using Firefox, Classic theme.
I've notice that on some Authors pages the Green/Grey dots, Flags and Arrows are displayed smaller than others. I eventually realised it's where an Author has less than 10 stories - the second digit pushes the table column wider.
The dot displays as 9x9 instead of 15x15. This appears to be due to max-width 100% in the img rule.
The least consequential fix looks like changing the th.lc1 rule in aBlue.css to width 2em.
(I also hate css)
