might depend on the theme;
check if you can influence the formatting of the hr with css;
http://www.w3schools.com/tags/tag_hr.asp
example for the style.css of the theme:
hr { width: 1px; }
for more suggestions, please post some links to your site to illustrate the various thicknesses.
to me, the hr look all the same size – in browser FF17
might be a browser issue; possibly try to clear the browser cache (press ‘CTRL F5’ or ‘reload’)
Dear Alchymyth,
Thanks for your reaction. But the problem stays.
I wish you and all readers the best for 2012
because formatting of a hr tag is more a css than a WordPress issue, possibly try to ask at a dedicated css forum like http://csscreator.com/forum
