There are two (2) ways to relaunch ggLeap after going to admin mode.
Method One (secured)
Simply restart the PC. This is the preferred (and recommended) method to do because it will allow ggLeap to start up in shell mode.
Alternatively, you can also sign out as your Windows user and sign back in. Use Ctrl + Alt + Del and click "Sign Out", then on the Windows User login screen, click "Sign In".
Method Two (unsecured)
1. Open Task Manager and then look for clientinterface.exe. Right click on it and select "End task" on the menu.
2. Go to C: and open ggLeap folder and launch clientInterface.exe.
NOTE: If ggLeap is launched in unsecured mode, the Windows taskbar/system tray will be accessible to the user.
