When a pop-up comes up my cursor will automatically go to a button waiting to click that button. Like if I have a download, as soon as the download window pops up asking if I want to download, the cursor will automatically move to the download button. I use robo form for my passwords and when that pops up the cursor goes straight over to the fill forms button. When I went to the control panel - mouse - pointer options, the snap to box is unchecked. I don't know why else my cursor would do that. It started about a week ago. And that is the only problem with my mouse. It doesn't mysteriously move across the screen or anything, just jumps to default buttons of pop-ups. Does anyone know what else would cause this?
