Can't use this computer since the mouse connection is terrible. It's not the mouse itself since its brand new and I have no issues with it on my other computer. While navigating the mouse pointer moves rapidly on its own and its not precise at all when I click to open folders, or click on hyperlinks. When I try to do a simple Save As operation, the mouse pointer goes bezerk and drops my files in the incorrect folder, resulting in me having to search for that particular file. It is a complete nightmare with this computer! I've reached out to the seller for help but no response!
