I'm not sure what you mean.

It there a problem with how the borders look?

There will always be changes that you will have to get used to.

Useful link. But unfortunately is doesn't say anything about my issue.

Your screenshot not describe your issue properly, can you elaborate more what are you looking for?

Look at the link ( http://spunit.tk/x/ff.jpg ). The Notepad window looks different. For example - Firefox borders are smaller, not the same color closest to the website, and the 3 buttons in the upper right is too much to the right.

I just think it looks so awkward with all the other winwows...

Sorry if I'm not so clear, tell me if you got it ;)

Anyone?
