Thanks for this. It does seem to be the cause of the problem although it only started after I opened a file on another (internal) drive. I also like smaller icons,the larger ones being too much like child's toys for my liking. > the >problem is that you have some item on your desktop that is sitting too >close to the drive icons. Move the offending item(s) far away from the >drive icons and they will stop "moving." Unfortunately I have my dock pinned to the top right corner using Tinkertool and for preference my drives are there as well. I seem to have to move them a long way from the dock so your comments on the coarseness of the grid seem to be correct. Their position does seem to have a random element about it does when I mount a firewire drive. X does seem to be full of these irritating 'features' (sigh). cheers, Chris
