The mouse hovers over a window and the scroll works in that window. If I Click that window, the keyboard operates the window (ctrl+F, page down, etc.). If I move the mose over another window I can scroll it, but the keyoard operates the window I previously clicked. I find that I have to constantly click a window before using my keyboard to amke sure it is the window in focus. This results in a lot of extra mouse clicks and aggravation. This could easily be solved by a little bolder lne around the active window. Then I would know shich window has the focus and would not have to click every time just to be sure.
Thanks for listening/reading
