Hello,
sorry I know this is an oldddd thread, but I'm having this problem now. I've made a word document with maybe 10 equations written with the inbuilt equation editor and it will not save. My friend had the exact same problem last week, and I thought maybe it was an issue with his laptop, but clearly not. I've done a lot of browsing through forums and webpages and cannot find a definitive answer anyway. D'you know how to fix this problem now? (Word 2007)
Thanks in advance
