The problem is:
when I insert parentheses, ( ) or [ ] or { }, and into them are
more than one line, the parentheses are displayed and
printed incorrectly. The parentheses are fragmented in two
or more parts.
Since these symbols (we call them "fences") are created with
fonts, you could have a corrupted font. First things first
though... I'm assuming you're using the fences from the Equation
Editor "Fence Templates" palette. Otherwise you'd be using the
fences from the keyboard (i.e., Shift+9 for an open paren, etc.).
There would be no reason for those to "break". The ones from the
palette are "built" by using a top and a bottom segment, plus one
or more straight middle segments. It could be that your system is
using an incorrect font -- perhaps one that has a shorter middle
segment than Equation Editor needs.
Please check your font settings in Equation Editor. Go to the
Style menu and click Define. Make sure "Symbol" style is set to
"Symbol" font. If it's set correctly, you could have a bad Symbol
font. The best way to get a new one is to download the MathType
fonts from our web site (they're free). You can get them by
clicking the link in my signature, and clicking on "Font
installers" in the "Free Downloads" section.
Better yet -- and this will undoubtedly solve the problem --
download the free 30-day test drive of MathType. This will
install the fonts, plus you'll have full use of MathType for 30
days. You can purchase it, of course, but if you choose not to,
it will remain usable in a reduced-features "MathType Lite" mode.
MathType Lite retains all Equation Editor functionality, plus a
few extra features.
