Problems with SacI

I am currently facing serious problems using the  SacI restriction
enzyme. I can cut a purified plasmid with it, but I am not able to do
a double digest within the same buffer. Nor can I do the digests
sequentially, i.e. digest with second enzyme first, gel purify
fragment, redigest with Sac I. So what else could I do? I have heard
that Sac I is extremely sensitive to salt, so should I try to wash the
fragment more extensively ??
