We're using Windows 8 Pro 64 bit on a Sony Vaio Ultrabook. This is a brand new touchscreen notebook with 8GB memory. When we copy a file or folder from any location and paste it to some other location, those files and folder are not displayed for minutes at the destination location except you manually refresh Windows Explorer via F5. We know the copied files or folder are there right at he destination because if you try to copy/paste the same file to the same location, the system asks if we wanted to replace the existing one! The weird side is it only occurs when the notebook is connected to the internet (either with WiFi or integrated 4G card) out of the office. It doesn't occur at the office wireless network, when the notebook is connected to the internet through the office LAN. I have never witnessed that ordinary fs operations such as copy/paste are effected by the connectivity state of the said computer.
No viruses, no worms,.. Any idea will be appreciated.
