MathType problems

Dear Scrivener users,

I started using Scrivener (Windows) with MathType because I need a lot of equations. But there are 2 problems: (1) the equation inserted is horribly blurry and cant’t be resized, and (2) when inserting an inline equation, it is no resized for the line and too big (and blurry, too). Anyone else having this problems?
