HTTPS + Snapshot problem

I've noticed a problem and narrowed it down to 2 plugins: WordPress HTTPS (which allows you to run the site under SSL) and Snapshot.

If I have WordPress HTTPS active and I activate the Snapshot plugin then something goes wrong with permissions and I get a "You do not have sufficient permissions to view this page" message on every admin page.

Deactivating the Snapshots plugin or the HTTPS plugin fixes this issue. It seems to be a conflict with these 2 plugins.

Please help!
