Here's what happens. Stock wifi Xoom. I plug in via usb. Computer running Win7 64 bit sees the xoom just fine. I can drag a file from either the internal storage, or the sd card onto my computer. But when I try to drag any file from the computer to the xoom, I get an error message saying "The device is either not connected or is not connected". I've looked everywhere and I haven't found anyone with this problem.
HELP! Any ideas?
EDIT to ADD: Weirder still, I tried a Windows system restore. Now I can drag a jpeg or .doc file, but no movie files, regardless of size or format. CRAZY!
