Here's an example of the problem. 98°F/36°C. In the "It's so quiet" thread the C and F are changed to lower case when I preview my post.
I've also tried not putting the degree symbol in and placing a space between the temp and the capital letter. The problem continues.
I've also tried 2 of my other computer and used a different browser, the problem continues.
Under this tab there doesn't seem to be a problem.

Would someone else go to the "It's so quiet" thread and see if you have the same problem. Thanks.
