Microsoft Works 4.x Displays Equations from MathType 3.5 and Earlier Incorrectly

The information in this document applies to:

MathType 3.x (Win)
MathType 1.x-2.x (Win)

Microsoft Works 4.0 (Win)
Microsoft Works 4.5 (Win)


I've created an equation with MathType. It looks fine in the MathType window, but once I place it into Microsoft Works, it resizes to the size of a 1 inch by 1 inch box. No matter how long or short, wide or narrow the equation in MathType is, Works stretches or shrinks the expression! 


The problem has to do with how MS Works deals with OLE (Object Linking and Embedding) objects. OLE allows two completely separate programs like MathType and Works to interact. MathType 3.5a and earlier used OLE 1 and as a result were subject to this bug in MS Works. Design Science has already reported this issue to Microsoft. We do not, however, know when or if Microsoft plans to remedy this issue.


Equations created with version 4.0 (or later) of MathType are OLE 2 compliant. Because Works can use OLE 2, this problem does not affect expressions created with MathType 4.0. If you are using MathType 3.5b or earlier, it is recommended that you upgrade to the newest version of MathType to circumvent this problem in MS Works. If you would like to upgrade, or have questions about pricing, you can do so on-line by visiting our on-line ordering page or you can contact our sales department at the phone number listed on our "Contact Us" page.
