MathType: an extra space is inserted after inline equations
The information in this document applies to:
- MathType 6.8 and later (Windows)
- Microsoft Word 2007 and later (Windows)
When inserting an inline equation, an extra space is inserted after the
equation in Word.
The space was added as a workaround to a known Microsoft issue that occurs
when inline equations are the last object on a line, causing
inline equations to appear raised above the baseline.
Since the inclusion of an extra space after an equation can at times have a
negative effect on formatting, there is a simple registry key that can be added
in order to prevent the extra space. To do so, follow the instructions below.
- Exit from Microsoft Word and MathType.
- Note: To "exit"
MathType means more than closing all open
MathType windows. It also means exiting the
MathType Server. This has nothing to do
with a computer network, and is normally running
when you have used MathType with Word. To check
whether the MathType Server is running, look in
the "Notification Area" in the lower right of
your screen, near the clock:
Click the MathType Server icon, then click Exit.
- Click to download the
registry key to your default
- Unzip the downloaded file. This will reveal a folder called
MTW68RegFix that contains a file called WordCommands.reg. Even
though the file contains the name MTW68, this
is not only for MathType 6.8. This works for versions
6.8 and later.
- Double-click WordCommands.reg to install this registry
key (depending on your version of Windows and your security
settings, you may be prompted
to confirm/allow this action).
- Note, adding this registry key will remove the workaround
and the potential for poor baseline alignment will return.
This will eliminate the extra space inserted after an inline equation. You
can edit this registry key to turn the feature on or off as required by your
work processes as follows:
Note: If you followed the steps above, you do not
have to follow the steps below. What follows is the process to add the space
back, should you need to do so in the future.
- Click Start.
- Type regedit in the Start Search box, and then press ENTER.
- If you are prompted for an administrator password or for a
confirmation, type the password, or click Continue.
- Navigate to the following registry subkey:
- Located in the right pane is a string value for
NoSpaceAfterInline. Edit the value as follows:
- To include an extra space after an inline
equation, value should be 0.
- To disallow an extra space after the
equation, value should be 1.
