Problem with forum display (Sub-forums)

Hey guys,

i just noticed, that there is a huge difference between my Chrome and my Firefox.
As an example:
In Card Discussions are 2 Subforums.
Instead of this:
Attachment 2115
i get this:
Attachment 2116

it's not only in card discussions, it's in the whole forum.

Is there any work-around or is that at least a known bug?
I don't want to change from Chrome to FF ^^

Already been discussed before here: http://www.shadowera.com/showthread....tegy-Sub-Forum

ok, thanks.
I'll stick to that topic.
