Can't Scroll in Customizer Screen

When I try to make edits in the customizer, I am unable to scroll down the static front page past the welcome screen. I’ve disabled all plug ins that were not recommended.

The page is

Are you sure you’ve disabled all plugins? Are the recommended ones updated to the latest version? This isn’t something we’ve came across before.
Check your plugins again please and send me an admin account to vlad[at] so I can take a look if that doesn’t help.

Hi Vlad,

all plugins are deactivated, including recommended plugins. I’ll email you now.

Thank you!

Just tried in both Firefox and Chrome and it’s working fine for me. Checked the console also and there aren’t any errors.

For some reason, the trackpad on a macbook loses functionality in the customizer feature. Myself and another administrator on the account were both encountering the same problem. Arrow keys work to navigate, as does using the side scroll bar, but no go for the track pad. Thanks for taking the time to help me figure this out.
