XFCE panel separator

Afternoon A1Users, this is my first post here but I'm glad I found this forum. I'm going to give a few things I've read on here a go to try and tweak the A1.

I'm very new to any of the Linux operating systems and I'm looking for a bit of guidance with my girlfriends A1 netbook.

I've launched the "xfce4-panel -a" to add new panel items. The problem I'm having is when I come to insert a separator into the panel, there is a "box" (so to speak) around the separator which doesnt match the same colour as the panel background itself so it stands out like a sore thumb. This "box" also covers the top of the panel where there is a long horizontal black line. I'm sorry if that bit didnt make any sense what-so-ever, but I cant even think how to explain it any better!

I've tried going into the ".config/xfce4/panel" and looking in the separator.rc (? I dont have the A1 with me right now so thats a guess at the file extention) and tried taking a stab adding a line of code saying "height="2"" to see if that worked, but even after a reboot this didnt work so I removed that bit and still stuck on square one.

I know screenshots would probably help a bit more but I dont have access to this A1 right now as it's at my girlferiends house.

Its not that bigger deal but I would like to get it sorted, mainly for my own experience, as I'm getting quite into this Linux stuff even though I'm not that good with it yet!


Any help is really appreciated,

Thanks
