Do we need ATM Deluxe under WinXP?

[Dr. Dietrich Grau]

Dear Y&Y Family,

the only member of this family who answered my two original questions so
far is Mike Prager, who uses ATM Deluxe. But where are the members of
the family, who work successfully with Y&Y TeX under WinXP without
having installed ATM Deluxe? Do they not exist at all?

With many thanks to Mike, who clarified many points, and to Christina,
who motivated him to answer my questions in more and more detail,

Dietrich Grau
