Need small assistance with custom theme problem.

[bhxtyrant]

Hello guys,
It's been quite a while since i have been here so i hope this is the right place to ask this since the forums have changed much since my last visit.

Well first of all i am using Vbulliten 3.5.4,a while back when 3.5.0 beta was in use i developed a custom theme which i got to work fine in both Internet explorer and Firefox.Recently we reopened our forum and after reinstalling the skin i noticed a small problem that only appears in firefox browser in the form of these white lines next to some table cells.I was hopeing someone could point me in the direction to fix this small annoyance.The screen shots below show the problem.The first screen shot shows how it should and does look in IE,second in Firefox.Thanks for your time.



I was also wondering if there are any real significant changes between 3.5.4 and the new 3.6 that would cause problems with usig a current theme as i would prefer to update to the latest version.

Just a bump for this since it's dropped down to the bottom of the list.Hopefully someone out there may know what causes this as it must be due to the upgrade from 3.5.0 to 3.5.4.
