This is an interesting bug I found in Windows 7 build 7077. It seems to affect the new "Libraries" feature. Follow these steps: - Open "Documents" library - Create a folder into "Documents Library" (for example "Documents\folder1") - Create another folder inside the first one (for example "Documents\folder1\folder2") - Create two folders and a file inside the last folder (for example create "folder3", "folder4" and "New Text Document.TXT" inside "folder2") - Order by "Date modified" - Try to delete the first folder in the ordered list (you should use Details View. So it should be "folder4") It seams that windows 7 do not delete the folder. The file has been actually delted, but Windows 7 do not refresh the view. You have to manually refresh it pressing F5! This bug shows up only if you use "Date modified" ordering. Is there any way to advise Microsoft of this annoying bug before RC1 release?
