Issues with hyphens in Caption changing to em dash

[KarenLRB]

I am having a problem where my hyphens in my caption numbers ar
changing to em dashes. Here's what I have set: in Caption dialog box
under Options, Label is set to Figure, Position set to Below selecte
item, Exclude label from caption is turned on; in Numbering, Format i
set to 1, 2, 3, Incluce chapter number is on, Chapter starts wit
Heading 1, Use separator is set to hyphen.

Everytime I insert a caption, the caption displays in my document wit
an em dash instead of a hyphen (so like 1(em dash)1. Caption Titl
instead of 1-1. Caption Title (with a hyphen)). I am using Word 2007 an
this is happening to all of my documents that use captions. It is als
happening on some of my colleagues documents using Word 2007 and Wor
2010.

Any help is greatly appreciated. Thanks

I'm wondering if this could be caused by AutoFormat As You Type, but I have
never seen the problem myself.

Immediately after the hyphen has changed into a dash, if you look at the
Undo drop down, what command is listed there?
