When I open a web page, I often hit PAGEDOWN to scroll the page.
Often, or usually (not sure which) nothing happens.
I then have to left-click the mouse on an empty part of the page, then the PageDown button will work.
Sounds that the browsing area doesn't get focus or a text area or input fields has focus, so you can't use buttons like page down.
Does Tab or F6 has any effect if this happens?
Typical. I go to see which sites are having the problem, and now I can't find one.
