Hi Rich, Desktop system with 8Gb Ram, 6 TB HD space on 3 hard drives and running a Intel core i5 CPU @ 3.30GHz. I have all the latest updates and service pack 1 installed. I have tried a new mouse but no go.... it is difficult to describe the exact problem but to try just that here is some more info: when you click on "New Folder" or right click and create new folder, the system creates the "New Folder with the name highlighted to rename it. I can then start typing in a new name but sometime it will close the option when I am still typing in the new name. I have experimented with it and created a new one, then I just leave it until it closes the rename option by itself. This happens after about 3 - 5 seconds without any input from my side.
I hope this help
