Thanks for posting trshaner, I was starting to think it was just me and I'd inadvertently changed a setting in IE9. I don't get italics in Chrome (Windows & Android) so it seems to just be IE (Win7).
Hopefully Adobe are on to this as it makes reading the forums much harder on the eye.
It's not a big deal, but I wanted to alert forum members so they didn't waste time trying to "fix" it. I tried replacing common screen fonts (Arial, Tahoma, etc.) in the Windows fonts folder, since a missing or corrupted font (i.e. Arial Regular) can cause the same issue.
It's definitely an Adobe server based issue.
The font-family: “abobe-clean, …” is what is doing it. If you edit the styles in IE F12 mode and remove this font-family entry in a couple of the BODY tag styles, the italics is gone.
The “adobe-clean” is coming from a style-sheet downloaded from use.typekit.com and so a way to defeat the italics is to assign use.typekit.com to the local loopback address by adding the following to your hosts file: 127.0.0.1 use.typekit.com
Thanks ssprengel that works! So what does Adobe need to do to fix this and any idea why it happened?
For anyone interested in modifying their Hosts file this link explains how:
You need to open the Hosts file using Notepad by right-clicking on the shortcut 'Notepad' in Programs> Accessories and select 'Run as Administrator.' Then type or paste in '127.0.0.1 use.typekit.com' as shown below:
