For the seperator, I noticed this too but there's only 2 ways of doing it..
1. make the top bar bigger.
2. make the separator smaller.
Making the top bigger for that looks weird (to me). I can edit the separator and put it for download here. That's probably the best way to do it but it means manually changing the images on your part.
EDIT: I can't seem to find the separator image....
For the left border, it's actually going all the way over in that pic. That's the only way to get the curves. Only fix for that is to remove the curves...then it looks (to me) less 'fancy'. If you don't use the tree, I could make a curveless version and then that won't appear. That's the reason I removed the tree highlight bitmaps because it looked offset but it wasn't.
And I'm glad someone is using the Olive version. I thought I was the only one.
Anyone using Deep? Haven't seen any replies on those since they were available.
Thanks for the comments. Penfold, let me know if you want new separator images.
Also note, I'm trying to make a new volume control but haven't had any ideas yet.
