cancel function

I cannot seem to get mathematica to cancel the exponetial function in the
following relationship;

in(1) =  eqn1 = a E^(I w t )(b + c x) == 0
out(1)= a E^(I w t ) (b + c x) == 0

in(2) = eqnw = Cancel[eqn1/E^(I w t )]
out(2) = E^(-I w t )( a E^(I w t )(b + c x) == 0)

I seem to think that cancel should reduce above to:

out(2) = eqnw = (b + c x) == 0

any help would be appreciated.
