Thanks Eric. This issue is unrelated to the zooming in and out.
Had a few people on the web try..same results…font size doesn’t adjust despite making changes via the browser. Looks like the layout may not be optimized for Windows 7 users. Have been able to adjust font sizes with no problems via other Genesis themes.
Have you tried with IE or Firefox on your Mac? Hopefully, there is a fix to this. Thanks again for the help!
