Most of you probably already know this, however, I found it interesting. I've only performed the benign test of creating a Firefox bookmark while sandboxed and then seeing if it is in non sanboxed Firefox and indeed it isn't. So I thought I'd delete a bookmark while sandboxed to see what happens, assuming in non sandboxed it would still be there, which it was. Here is the interesting thing though. I just randomly select a news article and mark it. I re-sandbox and it isn't even there. I came to realize that until you delete the contents of a session, when you sandbox, you return to a previous session. After I deleted the Sandboxie contents and added the bookmark un-sandboxed it was in the new sandboxed session. Point being, until Sandboxie contents are deleted you sort of return to the previous sandboxed session.
