Widen description column for issue navigator

Each version I have to find a different file to change to accomplish the customization of making the description column wider in the issue navigator. In 3.2 I changed the widths in styles/global_css.jsp (lines 799 and 806). This file doesn't exist in 3.3.1. Should I change global_static.css? If so, which lines?
I changed line 1156 from 30% to 70% but it didn't seem to have any effect. I see the font has been made smaller in version 3.3, which is OK. On your support site, it seems to show description wide enough, but not on my installation.
Thanks
