Problems with MathType’s Fences and MT Extra Fonts under Windows 3.1


The information in this document applies to:

MathType 3.x (Win)

Windows 3.1

Running MathType sometimes results in messages stating that the Fences and MT Extra fonts are not available on the default printer. The result is that fences such as parentheses and integral signs and some other symbols will not display properly on-screen or in print. The following procedure will solve the problem:

  1. Open the Windows Control Panel and then double click on Fonts.
  2. Look for Fences MT Extra. If they are in your font listing, select them by holding down the CTRL key while clicking on each one.
  3. Click on the Remove button. Confirm that you want to remove the fonts, making sure that Delete font file from disk is NOT checked.
  4. Click on Add and move to the \windows\system directory. A list of fonts will be displayed.
  5. Hold down the CTRL key while clicking on Fences and MT Extra (Note: Either font may have the words Plain or Regular next to the name). If the fonts are not listed, follow the instructions below under Reinstalling Fonts from MathType Setup.
  6. Now click OK. The Control Panel will properly install the fonts. 
  7. Close the Control Panel.
  8. Exit and restart Windows.

Reinstalling fonts from MathType Setup

If the Fences and MT Extra fonts are missing from your \windows\system directory, the following procedure will reinstall them.

First you will need to make sure that there are no files related to the two fonts in your \windows\system directory. To do this:

  1. Double-click on the File Manager in your Main Program Group.
  2. Switch to the \windows\system directory.
  3. Select Search from the File menu. Next to Search For:, enter fences*.*. Click on OK.
  4. If any files are displayed, select all of them by clicking on the first one and then holding down the Shift key while clicking on the last one.
  5. Select Delete from the File menu. Click on OK and then confirm that you want to delete all of the files.
  6. Repeat steps 3-5, entering mtextra*.* next in the "Search For" field.

Now you will need to reinstall the fonts using the MathType Setup program:

  1. Run the MathType Setup program from the original MathType diskette.
  2. Click on the Custom Install button.
  3. While holding down the CTRL key, click on TrueType fonts and Printer fonts from the list of possible options.
  4. Click on OK. The fonts will now install and Setup will ask you to restart Windows.

After restarting, the fonts should work fine from within MathType.


Additional issues for Windows 3.1 users

Two important issues to be aware of regarding Windows 3.1 are:

Unfortunately, the Symbol bitmap screen fonts that Microsoft supplies with Windows 3.1 do not match the TrueType Symbol font. In the Symbol bitmap screen font the lower-case Greek letters are italic, and the upper-case are plain. To avoid confusion, it is best to remove any Symbol 8,10,12,14,18,24 (<resolution>) entries from the Fonts Control Panel (you may have more than one for different screen resolutions). The TrueType Symbol font will now be used for all point sizes and lower-case Greek characters will be properly rendered and printed.

Note to PostScript printer users: Due to current limitations of Microsoft’s PostScript driver (version 3.5), italicized and bold characters from the Symbol font will print only as plain Symbol.
