There have been a few instances of weird scrolling behavior happening within Chrome for Win7 and Mac, and similar, but unrepeatable problem within Android.

Within Chrome for both Win7 and Mac, once you reached the bottom of a page then refresh the browser which would place you back at the top and tried to scroll down again, you were no longer able to scroll using the mouse wheel. You had to refresh again, or use the side scroll bar for the initial use to reset functionality.

Within Android (4.4.4), I noticed randomly 3 times now, when navigating to or from pages there will be a very rare chance that the page will prevent scrolling any further after the initial display of the content, seems to stop allowing scroll inputs after 1.5-2 screens worth of content even thought there is much more content. Has anyone experienced this issue?
