I cannot stand complex mouse behavior. I don't need any fancy gamer-type behavior from my mouse. What I hate most of all is accidentally dragging and dropping a file or folder somewhere. 

I could go to HKEY_CURRENT_USER\Control Panel\Desktop, and adjust the DragWidth and DragHeight to some absurdly high number, but it would be a lot easier if I could simply disable it completely. There is no option on "Taskbar and Navigation properties" to disable drag and drop. There needs to be a setting in Start 8 to fix that; does that setting exist, and I merely haven't found out where it's hidden? (Also: is v1.56 a free upgrade from v.1.03?)
