This has really thrown me for a loop so I'm hoping one of the MS Word gods might know what's going on. Ok, here's the deal:

I create a document in Word 2010 and save it as .doc. My coworker then opens it up in Word 2003 and alters it, also saving it as .doc. Finally, my boss opens the document in Word 2007 to proof it, again, saving as .doc.

The problem is, if my boss makes any alterations to the document, the formatting goes to hell after she saves. If she doesn't touch anything in the document, everything stays fine.

However, when she does alter something, the font will change style, size, lose its bold formatting, etc...

I set the default font on every single document. I then went through and set styles for each part of the document, making sure each style for formatted correctly.

This is only happening on my boss' computer and only on certain groups of documents. (We have documents for client A, different documents for client B, etc.. All of them created by me, all go through the above mentioned process, yet this only happens on the documents for client B and only on my boss' computer)

We tried checking to make sure her default font settings were correct, they were. Her advanced word settings also seem to mirror other computers that do not have this problem. We tried embedding fonts when saving, no luck.

I have no idea what the hell is going on. Any suggestions?

EDIT: Also possibly pertinent information: My co-worker using Word 2003 sometimes uses auto-text in the document. We tried checking the font of that auto-text and it too is fine.
