PDF (not the format, the function).

After a brief honeymoon with the ContinuousDistributions package, it has
been happening to me quite often that Mathematica refuses to calculate
probability density functions. Even more amazingly, sometimes it can
calculate cumulative distributions but will still remain clueless when
asked about the PDF. In those cases, if you ask PDF[dist,x], having
previously defined the "dist" as, say, ExponentialDistribution[1], it
will make the substitution for "dist" but will not calculate anything,
simply returning PDF[ExponentialDistribution[1],x]. At the beginning I
thought it was just a problem of the computer I was working in, but it
has happened also in other systems as well. Has this happened to
anybody else? What's going on here?

Please, to avoid overflow of the newsgroup, answer to my email:

Thanks!
