I have noticed in the last few weeks that whenever I restart my MacBook Pro (such as I just did in installing the Safari update) that all of the icons are rearranged to the right hand side of the screen in alphabetical order. This is 100% reproducible. It seems to have appeared after I installed the OS X 10.4.9 update. In the finder view options box, I have selected "snap to grid" and deselected "Keep arranged by." Have I missed a setting somewhere? Is this possibly due to some kind of corrupt Finder/Desktop preferences? If so, what file do I need to delete to restore it? Could it possibly be a PRAM issue? Thanks!
