Win-7 Ultimate +SP1 x64
I am new to FCXE, so perhaps I just misunderstand how this is supposed to work:
I see this picture on the "screenshots" page" ...

... which shows the file extensions right-aligned, as I would like to have them displayed.
I go to Tools | Settings | View | General tab | File/folder list |
I enabled the "Right align extension for list and details view" check-box, and save.
However, this has no effect on the display of the extensions, which are still displayed immediately after the filename (NOT right-justified), like this:

I closed and re-opened FC, and even re-started the computer, but still get no right-aligned extensions. When I look again at the configuration settings, the enable-box remains checked, just as I had marked it.
It seems that FC is not paying attention to this particular setting. Other changes I have made to the settings do work as expected.
Is this a bug for everyone, or do I just need to make some other adjustment?
