PhpBB3 BBCodes

I noticed that there is something wrong with my recent / Active topics at the top of my forum.
Scroll is working file, But as you can see on the screenshot, The bottom is not showing completely..
Any idea what could be the problem please?

nvm, found it ..

row_height : '43px',
In overal_header

It seems that it's diffrent in Firefox 10, Firefox 9 and Internet Explorer.. lol
Hight changes in those browsers

Correct i had to adjust mine also, it actually says that in the install.xml
