Whenever either of these 2 programs are downloading something, my bluetooth mouse gets lagged to shit: really choppy, etc. The moment they finish downloading (or if I close them), it's instantly 100% fine again. What can it be? It's a fast machine and according to task manager, CPU and RAM are mostly unused, either when these apps are on or off. When on and downloading, they seemingly take up almost no system resources. So what's the problem?
