That's why I'm looking for a officially approved way to intercept Trap #2.
There seems to be no easy way to do this with an AUTO folder program -
AES overwrites any changes, and so you have to write a TSR that waits
for AES to come up and then re-vectors trap #2. The tricky part of this
is waiting for the AES - how can you tell for sure?

Because of this problem, I still have one accessory that re-vectors
trap #2 - it's just much easier and seemed to be OK to me because
this way I can be sure that AES has been started when my accessory comes up.
If someone could show me a legal way for re-vectoring trap #2 in the
AUTO folder, I could get rid of this accessory.
