I just recently got an Asus Zenbook UX301LA, with Windows 8.1 and all the updates and have been having some problems with the trackpad. There is a setting in the windows 8 "Mouse and Touchpad Settings" menu which says "To help prevent the cursor from accidentally moving while you type, change the delay before clicks work." I've turned this setting to "No Delay (Always on)", but I'm still having problems with a mouse delay. When i type anything, it will take up to 2 seconds after I stop typing before it recognizes i'm trying to tap-click. Furthermore, my bigger issue is that I like to have my mouse/trackpad sensitivity set very high, but when I first start mousing, there is a significant delay before it actually starts moving the cursor. When it does start moving, it will jump a good distance to where it should have been based on my movement. The problem is it makes precision small movements next to impossible with this trackpad. Highlighting text is a pain because i will have to wiggle the mouse for a second before I can get it to recognize that i'm moving it at all, then go back to the point where I want highlighting to occur. In troubleshooting I have uninstalled the ASUS trackpad and tested with just the windows native drivers, and it still has these problems. Is this a bug with Windows 8.1, or something with ASUS laptops? It's driving me crazy with how frustrating it is to mouse.
