I've found this to be a problem for months now, though only about 30% of the time; sometimes files downloaded in Chrome will be in some way suspended, and Explorer can't move or rename them (it just hangs indefinitely on the copy dialog or hangs when I try to rename them). Killing all Chrome-related processes makes no difference. Killing and restarting explorer makes no difference. This is occurring across multiple Chrome versions and on many, many new customer machines with both OEM and our own fresh installations of Windows 7 and 8. It happens regardless of User Account Control status. Thoughts?
