Why can't I scroll horizontally in grids when using Mac OS X Lion or newer?

Apple changed the way scrolling works on Mac OS X Lion which may prevent users scrolling in Layer grids when certain conditions occur.

On ultra-portable devices which run iOS, that may be a good idea.  However, on Mac OS, it hides scrollbars for items which require them.

Restoring OS X Lion Scroll Bars

Fortunately, you don't have to live with Lion's scroll bar defaults; you can change them to meet your needs or preferences.

1. Launch System Preferences, either from the Dock or from the Apple menu. If you're trying Lion for the first time, you can also launch System Preferences from the Launchpad by clicking the Launchpad Dock icon, and then clicking the System Preferences icon.

2. Once the System Preferences window opens, select the General preference pane.

3. The middle section of the General preference pane controls when scroll bars appear and a few additional scroll bar options.

4. To return the scroll bars to their pre-Lion functionality, select "Always" from the Show Scroll Bars options.
