I have a couple of problems with the way windows are working: 1) Why does the scroll button speed up scrolling when I click and hold it? It make it impossible to see/read the contents of the window when it starts accelerating. E.g. in Firefox, holding the scroll button causes the page to scroll down faster and faster. Ditto Finder windows. Any way to kill the acceleration and have the window scroll at a constant speed? 2) Is there any way or 3rd party app that can make windows snap to each other/screen edge?
