That sounds like a bug. Hmmm. Yup I can confirm it. It is a bug.

Same here with last Sunday's CVS snapshot. :(

Let's see... This *works*.

Wait a sec... This works too:

For some reason, the macro definition of "VM -T" isn't working. Definitely 
a bug[1].

Remember that if you use .VM instead of .VM -T, you are using relative 
movements,  thusly the actual margins are top = 25v + 7v and the bottom is 
25v + 5v. Unlike .VM -T you need to do margin resetting by yourself (that 
is, .VM -25v -25v).

Equally.
