NBME (National Board of Medical Examiners) Mac Secure Browser - Mission Control Multi Touch Gesture Problem

If you download NMBE Web-Based Testing browser, Mac Secure Browser, on Macbook Pro, and your trackpad functionality does not return afterward (even after uninstalling the app):

Access the Terminal on your Mac, and using the Terminal, issue the following command:

defaults write com.apple.dock mcx-expose-disabled -bool FALSE

Followed by:

killall Dock

Also maybe necessary, but I'm not sure:

(1) System preferences -> Trackpad. Make sure all settings you prefer are checked.

(2) System preferences -> Accessibility -> Pointer Control -> Mouse & Trackpad -> Trackpad Options -> Make sure "Enable dragging" is checked with "three finger drag" or your preference.

Shout out and much gratitude to NBME Technical Support for helping with this.
