crashes in office (excel and word for example) on macbook pro

I have a Macbook Pro that I have had for about 4 months now. I have
office installed on it (and have applied all updates including 11.3).
Office works fine, but is EXTREMELY finicky. For example, I have found
I can't right click on anything without risk of crashing. I have two
reproducable crashes.

With Excel

1. Open a new workbook
2. Enter something into the first cell (say the number 5), hit enter,
and than click back into the cell.
3. Now right click to open the context menu and boom crash.

With Word

1. Open a blank document.
2. Type a word or two (say new car)
3. Highlight 1 or more words
4. Right click on word to open context menu and boom crash.

Note

These context menus work until you actually enter something into the
program (you can right click in both examples before you type anything
in, but once you try and do it on text you have entered, it crashes).

Is anyone else experiencing anything like this, or is it just a whacked
out installation I have?

Thanks
