bug reports..

Steve,

I vote to keep the bug reports coming.  It's easy enough
to sift thru them.  Users in the group are bound to be able
to provide suggestions, at least some of the time.  This should
also help "naive" users come up to speed, and should certainly
help make Mathematica a better tool.

Some apparent bugs in version 1.1 for the MacII:

Limit[ x/Sqrt[x^2], x->-Infinity ] returns +1.  This error
seems to mess up the integrator on some functions when
integrated on {x,-Infinity,a}, as e.g. 1/(x^2+1)^(3/2).

Integral[ x b^(a x), x ]
then Together[ D[ %, x ] ] doesn't return x b^(a x).
