Jon, I've noticed the same problem. I have a folder on my iDisk that I like to access frequently, so I dragged it to the lower portion of the Finder sidebar. It used to stay there permanently, but now it disappears whenever I restart the machine. However, if I make an alias of the folder and save it to my regular hard drive, and enclose that alias in a folder, I can then drag the folder to the sidebar and it will stay there between restarts. When I click on that icon in Column View, the alias is there, and I can click on it and navigate the folder on my local copy of iDisk without any problems. This was not the behavior in Panther.
