Using WP 2.7, I ran into the problem on two different computers in two different locations.
I don’t think it’s a code problem, but may have something to do with Firefox.
When you make multiple edits to a post, the font will get small and render the blog smaller in Firefox.
It displays fine in IE.
Blogs that went small on me earlier this morning at home render fine on FF on an office laptop. I expect the blog I am seeing small now will look fine in FF when I get home.
I just checked the site on Safari on a Mac, and it looks great.
As far as I can tell, there is a problem with multiple edits and display in Firefox. Rebooting does not help. I may reinstall FF to see what happens if you do a repair on the install.
