Thats quite alright..no problem. Now were on the same page
The only problem now is im not quite sure whats causing your problem
So, we have My Computer open and are looking at Shared Documents and "A's" Documents. From here, right click a's docs and go to the sharing tab. Make sure nothing is checked, if nothing is and the problem remains you need to open your Shared docs and make sure you dont have a
My or A's documents folder in it. Im kinda taking a shot in the dark here, not a problem that i've seen before.
