General ⇒ Font 'cmbright' not scalable

[Joske]

I'm using the font 'computer modern bright' (see http://www.ctan.org/tex-archive/help/Ca ... right.html) for my dissertation. In the preamble I have

\usepackage[T1]{fontenc}
\usepackage{cmbright}

Computer modern bright is a scalable vector-oriented font (also according to the manual), but after compilation it seems that the characters are bitmaps in both the ps and pdf files (also when the extra option -P pdf is used for dvips): if the characters are enlarged then they are not smooth but block-like.

Does anybody recognize this problem and how can it be solved?
Thanks a lot!
