@CrystalRenee0301. Check your settings if you have MouseTrails on and if you do, turn them off. As an alternative, change to windowed or full windowed mode
2. This also can be related to having notifications enabled in Windows. Although you may not see the notification itself, your computer thinks you're clicking that and not the game. Disable notifications while you're playing and see whether it helps.

3. Turn off Origin in-game
Origin/My games library - right-click on the cover of TS4 choose Game Properties, you can disable Origin in Game for that
4. If all these three ways don't help, go to Documents> Electronic Arts> The Sims 4 and find the Options file - the one with a toothed wheel. Delete this file. The game will create a new one when turned on. However, if you changed something in the game options you have to set it again
I don't work for EA
