Micros~1 has once again featurized a security hole of unfathomable
crapitude. For some reason, IE still thinks that files of certain MIME
types are appropriate to be downloaded and run without question. After
all this time, with all the worms that have been written, they still
haven't decided to change the rule instead of patching in various
exceptions to the rule over time

Many products have security holes, but this is not a "hole".  This is
an institutionalized masochistic suicidal tendency on the part of
Windows and the associated "applications" that fester around it.  As
an analogy for the Internet challenged at this Internet company, this
is equivalent to a random person walking up to you on the street,
giving you a syringe, and telling you to inject yourself.  I have
never in my life seen a piece of software that just says "okay!" as
enthusiastically and as often as the mangled heap of bits from Redmond
do.

I advocate the complete destruction of any Microsoft products
currently in use at Wego Systems, preferably by fire.  I cannot
understand why individuals would collectively subject themselves to an
operat~1 that makes them the laughingstock of anyone they ever
correspond with.  Oh wait, that's because the people they correspond
with also use the same thing.  The world for some reason relies on a
set of power tools that thinks it's funny to jump up every so often
and drill a neat little hole in the owner's leg.  And people _pay_ for
this!  Don't think, little bugs, just fly toward the pretty buzzing
light....

Anyway, until your machine is patched, you shouldn't read, well, any
email whatsoever.  Sorry.
