[QUOTE="Raz0rEdge, post: 1939593, member: 110816"] It's normal for the entries in the Activity Monitor to shift since you're sorting by CPU usage and that varies by what each application is doing. The list only helps when you're facing the problem, during "normal" operation, it doesn't provide much value. So when things seems are they are going slow, you should check Activity Monitor and check the overall usage at the bottom of that page. Then take note of what apps are on top of the list. If it's an application you are using, then that's one data point. If it's something like [B]kernel_task, [/B]that's a different data point. So you need to determine the pattern and ideally the causes. We are not going to be able to do this for you, you have to learn to do it yourself and track down the culprit (if there is one). As far as your scrolling goes, that's called drift and happens depending on the mouse you are using. If you are using a mouse with a scroll wheel on it and it's malfunctioning a little bit, then you'll see subtle scrolling until it settles down. I have a Logitech MX Master mouse that has a very smooth wheel that allows me to scroll through a page very quickly, but if I change focus to another application while the wheel is settling down post spin, it will scroll the new application like crazy as well. But this is my own doing an fault, so I keep better control on the wheel. If you are using a Magic Mouse or Magic Trackpad, then this should not be happening since there's no wheel and both of those devices require you have 2 fingers on it to scroll the page, a single finger just moves the cursor.
