I was able to get Calibri to work. That was the only one that would work for me.
Just a side note about this issue. I have created about 20 different modules and only some of them have this issue with the review area and for me, it's only on Internet Explorer. What's even weirder is all of the modules were recreated from the first original module I created, so all of the settings are exactly the same. The only difference is the content itself. It's really quite random. I took a module that successfully showed the review area in Helvetica and copied the slides from a module that was showing times new roman font. When I exported the module, it was showing times new roman again. *sigh*
Things like this makes me want to switch to another program, and I just might have to. Not professional at all!
Good luck everyone!
