nascode, chrome does that with most files, it's nothing that Edgar can fix on his end. As for norton, you should probably switch to a less terrible AV program, like Microsoft Security Essentials.
As for the update, I was looking at the spec doc finally (I'm a high tier backer from Kickstarter). I was wondering if you had a document to explain the concepts you are using in the spec itself? I was thinking about busting out an implementation, but based on the SCML document alone I'm left mildly confused.
