I've a problem with my computer. When I'm opening a file thats in a folder (also in desktop folder) this folder hangs (I can't interract wih other files in folder or close or minimalize it), and the file opens afer almost a minute. It doesn't matter if it's a small txt, pdf, xls, doc... But I've noticed that when I turn my network connection off, then the problem dissappears. I've used net use to find out if i have anything mapped but i don't. This is a company computer, but nothing changed recently in IT.
