With the recent update to Chrome OS you may notice that your touchscreen chrome book is not functioning correctly. When trying to blend sounds, the chrome book wants to take you back to the previous screen. Here is the fix!
1.) Open a new tab
2.) type in chrome://flags in the address bar
3.) Control+F to bring up a find window
4.) Type in overscroll. This should bring up the option for Overscroll Navigation History. Disable that feature.
5.) Restart browser window
Your chrome book should function properly.
