Copy/paste concern: fonts getting changed

I think this sounds similar to a problem my friend had once.. & it was caused by the font missing or not recognised by Windows. I could be way off base here, but anyway, we found a CD with thousands of fonts on it & installed the missing font. After that, it appeared correctly. If you go to control panel (WinXP) and go to the FONT folder, is the font in there? If not, I beleive you might have to add it. If you still have problems, pls post them here. Pls also provide the operating system version and also identify the actual font thats missing.. That is, what does InDesign see the font type as? Rgds,
