I have two brand new Asus N550JV laptops here at work. I took them out of the box, installed the Windows Updates required to get the Windows 8.1 update to install, ran through that, then ran through all the remaining Windows updates.
On one of the two machines, I installed all the newest drivers on ASUS' web site for the N550JV. On the other one, I left it alone (there are various Win 8.1 related driver issues that need correction).
On both machines, if you open the Start screen and then use the two-finger scroll, when you let go of the scroll and then move the cursor it clicks on the exact center of the screen. When scrolling from the main Start screen to the All Apps menu, this results in launching ASUS Install and closing the Start screen. I uninstalled ASUS Install, thinking this was the issue, but it then just started clicking on ASUS Instant Key Menu.
The theory that it's simply clicking in the center of the screen was further cemented by using the arrow key in the bottom left of the Start screen to go to All Apps, then two-finger-scrolling back up to the regular Start screen. It launched Maps... the tile in the center of the Start screen.
This is absolutely driving me up the wall. Any ideas?
