[Axiom-mail] sqrt(-1) and %i |

Dear Axiom users;
I have a problem converting expressions involving sqrt(-1) to
expressions involving complex numbers and the symbol %i.
For example this works:
(2) -> p:=sin(1)*sqrt(-1)
+---+
(2) sin(1)\|- 1
Type: Expression Integer
(3) -> p::Expression Complex Integer
(3) %i sin(1)
Type: Expression Complex Integer
but not if through some more complex computation I end up with a type like this:
(4) -> q:Expression Fraction Integer:=sin(1)*sqrt(-1)
+---+
(4) sin(1)\|- 1
Type: Expression Fraction Integer
(5) -> q::Expression Complex Fraction Integer
Cannot convert from type Expression Fraction Integer to Expression
Complex Fraction Integer for value
+---+
sin(1)\|- 1
-------
Can anyone find a way to accomplish this coercion?
Regards,
Bill Page.
