Mathcad 14 and Print Preview crashing is a known problem, that should have been fixed for the vast majority of users in M020. However, even if you still have that issue, it should not be affecting Mathcad running. I suggest you contact technical support at http://www.ptc.com/support/mathcad_contacts.htm if you are a single user. If you have maintenance, you can contact them through your maintenance account.
