See Dr. Bryan Jones in order to obtain the MathType installation CD as well as a license. Some basic hints:
Note: The above tips are accessible from MathType tab, and some are
available in the New math type window that opens up with every new
Word places some default space around embedded objects to make sure that none of the text runs directly against the objects. Also MathType places a small amount of padding around the equation so that Word displays the equation properly. This can be adjusted but Word can occasionally clip or improperly display the equation without this padding. By changing a variable value in your registry, you can add "picture padding" around your equations so that none of the characters in your equations will be "shaved" and thus omitted. Editing the Windows Registry is not something we suggest for novice computer users. Please be certain you are comfortable editing the registry and have backed up your registry before proceeding.
Quit MathType. Make sure that MathType is not running in Server Mode. (Look for a small icon in the corner of your screen next to your system clock that looks like a stack of three square tiles with a blue sigma on the top. If it appears, double-click on it and choose "Exit" to quit MathType's server.)
From the Windows Start menu, choose Run. Type in "regedit" without the quotes. The Registry Editor functions very much like Windows Explorer. The interface is composed of two primary windows. In the left window, expand HKEY_CURRENT_USER by double-clicking on its folder icon or single-clicking on the boxed-in + beside it. Inside it, expand the Software registry. Inside Software, expand Design Science, then DSMT5, then Windows. Across the bottom of the Registry Editor window, you should see:
My Computer\HKEY_CURRENT_USER\Software\Design Science\DSMT5\Windows
In the right window, you should see a small AB-scrap icon next to a Data called PicturePadding. Double-click on the icon. A window will appear. The default Value data is 2, which means there are currently 2 pixels of padding around your MathType equations. By decreasing this number, you can decrease the padding.
Change the 2 to a 1. Click OK. You should not quit the Registry Editor yet. Return to a Word document in which you are experiencing clipping. Run the Convert Equations command from the MathType menu and update all the equations in your document. Please note that changing the picture padding defaults can result in erroneous display within Word including portions of the equations being clipped and not displaying at all.
Update: For MathType 6.0, the appropriate Registry Editor key is: My Computer\HKEY_CURRENT_USER\Software\Design Science\RSEE4\Windows. Editing the DSMT6 PicturePadding didn't seem to help.
