DIM doesn't get confused when you store the icon positions at one screen resolution and then restore them at a different screen resolution. In other words, if an icon is at the bottom right corner of the display when the icon positions are stored then that icon will always be placed at the bottom right corner regardless of the screen resolution. There's only one application that I know of which does that, but they want money to do it. Other applications/scripts allow you to save multiple icon positions at different screen resolutions. That's fine if you want to adjust your icon positions for each screen resolution you use. My question is why? You got a Mac sitting in front of you, let her do it.
What's new in this version:
Desktop Icon Manager 2.0.2 will now not reset the Desktop's "Arrange by:" option to "None" unless it must (e.g. screen resolution changed). The icon is now correctly done according to Apple. Minor tweaks to documentation.
