Important bug in group members

Hi I wanna show you a bug in Group members that happens in IE7 and Mozilla Firefox 3.0.5, and I wanna ask for your help cause I think this bug is on your sites too! Look on the screen

You observe that the second row of members in Firefox and IE7 cover members names from the first Thx nad im waiting for your help please!

Into witch Theme?
I can not check this out, because I have not so many members in groups... But It looks me a theme problem with rows 
Is there a site who I can visit to check out please?

hi! I found the problem it wasn't in theme... in engine i deleted the height from groups.css

.group_member_pre. and it is all ok now... also I added padding:20px to make space between rows...
