Mouse latency

I'm taking a game design course and my teacher made an awesome game. However, this game stopped working recently and I've been helping debug and ran into a wall. There was a lot of performance issues, with an actor that rotates to cursor and spawns actors on mouse click acting up. So, I made 2 actors: one that changes from red to green every second, and one that is red when mouse button is down and green when it's up. It turns out, the game moves normally (first actor still pulses every second) but the one that changes on mouse clicks acts up (stops receiving mouse clicks/gets stuck thinking mouse is down) I didn't see any info on this problem in a series of searches. Any help would be much appreciated.
