A late answer (better than none).

I've had this problem now a few times (with Excel 2010). The solution that has always worked (so far) was: remove conditional formatting, in particular if it contains UDF as conditions. As @LanceRoberts wrote in an above post, it's ultimately due to UDF calculations "overriding" the Open event, but I've found that those are particularly harmful if used in conditional formats.
