On multiple computers we have recently started experiencing the same problem. When Windows Explorer is open, we try to type a computername or IP address into the address bar. While typing, Windows Explorer refreshes and clears out what we had typed. This is especially annoying when it happens right before you press enter. The timing appears to be fairly random but under 5 seconds. I have noticed posts via google that blame VPN, firewall, antivirus and other pieces of software. We have none of the named software installed on any of the computers. Our feelings is that this behavior is tied to a recent Microsoft update as on many of the affected computers, that has been the only installs (no 3rd party programs allowed). Has anyone else experienced this issue and how can we cure it?
