Also, the IDQ.dll file properties do not show what MS indicates on their
bulletin:
"You've installed the patch correctly if IDQ.dll has the following
properties...
Date: January 26, 2000 Size: 193,296 bytes"

Has anyone heard from Microsoft about this?

This test is to see if you're vulnerable _before_ you apply the patch. After
you install the patch you _will_still get the same message.
