"Multiple Entry" Schengen visa

[Bluebirdjones]

Question:
Many on here have applied for, and received, a multiple entry Schengen visa.

However, how many have used it to enter another Schengen country at a later date,
and were there problems ?

(ie If you get a "multi" from the French Embassy, it does state that France should be your
"entry" point into the Schengen area, and France should be the principal area of travel).

..... so, has anyone used a "multi" issued by France, to fly DIRECT to eg Spain.... and how /
what was the reaction of Spanish immigration ?

Thanks in advance
