I m on a website using EVO 1.0.10, Quickmanager 1.5.5 Tiny 3.5.8.
We cant seem to scroll down to the content as a work around I changed this line in the colobox.css
Check your browser addons or plugins. I had this issue with FF in the back end but not when I disabled all the addons. Re-enabeling them one by one found the offending addon. I can scroll again. Worth a try...
I've disabled all plugins and extensions of firefox : no more quick manager bar...
I've change the css of colorbox, no more quick manager bar...
in Explorer, no problem very strange behavior of firefox.
So i'll use explorer for the last website i've made, firefox is ok for all my previous websites !
