Hmm I wonder if this is causing [url=http://mediamonkey.com/forum/viewtopic.php?f=6&t=31055]this[/url]

Reproducible here too, thanks for the screenshots/explanation.

Here's an easy way to reproduce:

1. Add a large number of tracks to Now Playing (so that now playing panel scrollbar will appear)
2. Enable Now Playing panel (View | Now Playing)
3. Dock panel to right side of MM
4. Notice inside of the panel that there is no border on the other side of the scrollbar or columns
5. Move mouse over close button, but watch the scrollbar. A few pixels will be cut off of the right side of the scrollbar to make room for the border
6. Bring the mouse back to the scrollbar. The border now disappears.

If possible, a good solution would be to have no border on the right side of the window in the right dock area and no border on the left side of the window in the left dock area. It would also be nice if the titlebar had no border or at least a border on both sides to resolve http://www.mediamonkey.com/forum/viewtopic.php?f=6&t=36387

1:
you see fixed window caption with 2 pix border,
(Window/scrollbar got no border!)

2:
When you cross the close button from caption with mouse,
it's showing than 2 pix border on window and cut the scrollbar!

3:
select hedear cut again border.

if you select next song ,border disappears

i dont know if this is possible but
i think a good sulution would be to have no border on right side from window
in right dock area and no border on left side from window in left dock area,
or/and no border by side the caption like window under it.
