ISO: Help me with Hawaiian Sweet Bread recipe

I tried the following recipe in my Panasonic bread maker (capacity 1 & 1/2 lb. loaves). It rose so high that the bread got all over the top of the breadmaker and made quite a mess. But the bread was delicious! Anyone have a suggestion as to what to do? Use less yeast? Alter the proportions of other ingredients? Please help, because otherwise, this recipe was a keeper. Thanks!
