For some reason, my iTunes icon has decided that it won't stay in the Dock. When I open it, it will sit on the right of the dock, like any application that doesn't have a permanent place on the Dock. It shouldn't - it always used to live in the middle. However, if I drag it back there, it stays in place about 1 second, and then shoots back over to the right again. Even if I select "Keep in Dock" from the context menu, that clears as soon as it moves back to the right. As soon as I shut down iTunes, the icon disappears. I've done a lot of searching and it seems that loads of people have suffered this problem with various apps (i.e. it's not iTunes specific), but I've not yet found a solution. Some people have suggested it's a .Mac/mobile me syncing issue, but I've turned syncing off, reset syncing data, overwriting the mobile me Dock with my Mac Dock, everything I can think off - besides, the icon moves to the right so quickly that it's not had time to sync. Another suggestion I've seen is deleting com.apple.dock.plist, logging out and back in again. Even doing this and starting with a "virgin" Dock still sees iTunes refusing to stay. Oh yes, I've tried repairing disk permissions too. Any suggestions - please?
