I have a very strange problem with math.stackexchange.com. The normal text on the pages (and on these meta pages, too) is displaying in both IE and Chrome in bold italics on just one of my computers. I have a couple of other computers, and the fonts display normally on those.
I did 'inspect element' in the Chrome browser, and it looks like the font family chain is Georgia, Times New Roman, Times, etc.; nothing about bold and italics, so it looks like the pages are ok.
The displays are the same (both wrongly bold italic) in Internet Explorer and in Google Chrome, so it doesn't look like a browser issue.
The computer is super vanilla, many fewer applications installed on it than on the others, so I think it's unlikely to be something broken in Windows on the computer.
The MathJax formulas display correctly, it's just the normal text is off.
I couldn't find any way to set default fonts in Google Chrome (I'm not a browser expert).
Could this be a "Themes" thing? Do Windows themes reach inside browsers? Any help would be appreciated.
UPDATE: I went into the Windows fonts interface in Control Panel, and the only variation of Georgia that was installed was the "Bold-Italic" variation, so that explains it. It appears that my computer was so vanilla that Hewlett-Packard decided, on my behalf, to remove fonts that I couldn't shouldn't wouldn't possibly ever want. After all, a couple of wasted megabytes from a rare font on my 1TB hard drive could be critical! (sarcasm). My attempt to copy the missing fonts from another computer has created some new problems.
ANSWER: Copying all fonts from another computer and rebooting fixed the problem for now.
