When viewing some emails in Lotus Notes 8 the email scrolls very slowly when scrolled with the mouse wheel. Scrolling with the mouse wheel works fine other times, and there are no problems at all using it with other applications. Does anyone know how I can fix this? Thanks.
Sorry to tell you but there is no fix for this.
Notes is inherently broken in the sense that it doesn't act or work like a Windows application. While it does do most things in a way that is familiar, some things are just not what you expect. It has been this way for every version since dawn; I don't see any chance of it changing for the better this century.
Specifically, scrolling a window that contains text requires much more mouse-wheel-turning than the same number of lines in e.g. MS Word or Notepad. If the Notes window contains an image, it will become even slower/harder to scroll for as long as the image is partially visible.
Notes just is that way. Accept it since none of us can change it.
