So this is a bit of a weird one. I've had my UTechSmart mouse for a decent while, always worked properly with no issues, but after purchasing a Razor keyboard and installing the drivers for it, the mouse no longer accepts user input. The conditions of what I can do and what I can't do are very unusual: I can move the mouse around and if the mouse is over a selectable area of the screen it properly highlights the element, but clicking the mouse has no effect. The only way I can restore mouse functionality is to open the Task Manager, which oddly enough I can click on anything in the Task Manager without issue, and then find and kill the task "Keyboard and Mouse Processing". I've tried downloading the latest drivers with both mouse and keyboard without success, and I need to kill that task every time the computer reboots to be able to use my mouse properly.
