Hey sjts,
I've never had that happend. My upload always starts, then stops and that error code pops up.
Do you think your problem could have something to do with your pop-up blocker maybe? I know that has given me problems in the past if I don't have it turned off.
Here's one other idea that may or may not work. I've had problems in the past with Auctiva and other sites as well that use something called ActiveX. I'm not very computer literate, so I'm not sure what it is. Someone told me problems like you're having can be due to some of the security settings on the computer. I've found if you will hold down your CONTROL button before you click on whatever it is you're trying to do, it I guess bypasses whatever that security setting is and lets it work. I have to do this to get the category selection to work when I'm listing through Auctiva. Otherwise I just get a blank pop-up. Like I said, this may be totally irrelevant to your problem, but it's the only thing I can think of you might try. Let me know if you have any luck!
