Malinda, If you have Bitstream, no ned for the Font Thing, both accomplish the same job.
Open Bitstream Font Navigator, and you will see an explorer type of window. Upper right window is installed fonts. Upper left window is a list of ALL fonts, with a checkmark on the installed fonts.
Uninstall all except for the necessary windows fonts and any fonts you use on a regular basis. 100 or so fonts max. This will simply uninstall fonts, but you can reinstall them with a click whenever you need. You can create Groups of fonts that you use for certain project to install and uninstall with a click.
Whether this is the cause of your problem or not, it is good practice.
Also, this cleanup will help you toubleshoot. If youn uninstall the fonts used in the doc you are having troubles with, Corel will make a substitute when you open the doc. See if the problems persist. If they do, you have eleiminated the fonts as the cause. If the problem goes away, you have a coruupt font clogging up the works.
hope this helps When in doubt, deny all terms and defnitions.
