5. VERY IMPORTANT. You need to DISABLE the auto-update for Dropbox until the new stable version is installed (when it eventually comes out) and you stay on this version. 158.4.4564. To do that: open Task Manager (CTRL+ALT+DEL) and go to the PROCESSES tab. Scroll down to BACKGROUND PROCESSES and keep scrolling until you get to "Dropbox Update Service (32 bit)" and click on that to highlight it. Then right-click and select "End task." That will disable the auto-update TEMPORARILY.
