I can not remove a couple of icons on my desktop. They seem to be inactive, I can not open the properties, delete them, or change the icons name. I can drag them to the recycle bin but it wont take them. They are all related to Autocad 2000i. Also I have put some files in my Autocad folder and cannot open them. This is just some of the icons and files that I have transfered from another network computer. All my other Autocad icons and files open just fine.
