I have my default documents folder set to "D:\Dropbox\My Documents". It is the only folder in my Windows 7 Documents library. When I tell Dopus to go /mydocuments it will go to "D:\My Documents" but it will also display all the files and folders as if it was in "D:\Dropbox\My Documents".
Obviously, my documents folder is synced with Dropbox. I don't know if that adds to the wierdness. But, why does Dopus show the folder to be in a different location than it is?
