Hi:
I'm using beta5 and I enabled the old tab interface (View->Tool Windows->File Tabs).
Now, when I click on a tab in the old interface (below the editor window), the editor window contents do not change to the new file. It works with the new tab interface though, but old one seems broken.
I'm still using the old tab interface because I find it easier to read (no gradient and lighter colors in tabs). Also, there are some features there that are not ported to the new tab interface yet.
Thanks,
Rob
