Well, my fix only worked for a bit it seemed. ^^;
It’s back to doing the same thing. I don’t have a secondary monitor and the one I am using is a TV (actually) I have connected by HDMI. My GPU is NIVIDIA GEForce. I don’t know if any of this information helps.
Thank you both for the messages, but I think I fixed it. I went into preferences and changed a couple of things and now it works. If I need more help, however, I’ll make sure to come back.
