How to remove window outlines?

[PaulyP]

Hi.

Just installed build 10158. Is there a way to disable the horrible window borders (the thin "theme coloured" line around the outside edge of the active window? It looks terrible and I'd rather it had no line at all, like when the window is not active.

If you know how to do this, any help would be much appreciated.

Thanks.

PS - Actually the window border doesn't disappear when not inactive, it just turns grey... which also looks terrible.
