Problems with blank odt files on one Windows account

My wife opened an odt file this morning with Writer and discovered it was blank, although the status bar at the bottom had nonzero word and character counts. I created a new document and the cursor did not show up in the body of the document. I could type and the status bar would show words and characters, but there wasn’t any evidence of it on the screen. I switched the font from the default to Garamond and suddenly things worked fine. However, I wasn’t able to apply the font change to existing documents. I uninstalled and reinstalled LibreOffice but the issue persists. I emailed the file to myself and on my account on the same computer it opens fine. I tried starting in safe mode with and without the graphical acceleration options and none of those configurations fixed the problem. What can I do to fix the program on her account?
