If you are using a Mac and having difficulty scrolling, especially on the Attendance tab, try the following steps.

The best remedy for this issue is to turn the option for Show Scroll Bars to "Always" and that should resolve the issue.

• Click the Apple menu at the top-left of the screen, then select System Preferences.
• Next, select the General preferences pane - it’s the very first one, up at the top.
• Under the “Show scroll bars” heading, you’ll find three options: “Automatically based on input device,” “When scrolling,” and “Always.”
• Go ahead and select that last “Always” option. You’re done!
