Folders and downloads showing up on other users account???

I'm new to windows 8, There are two accounts on our laptop. My mother is set as the administrator. I am trying to figure out why when I download something it shows up on to her desktop. Also, I have opened my browser and her google settings and bookmarks have come up when she has not logged in to her google account from my user account. I just downloaded aim as well and when she logged in to her user account my buddy list window with my saved information pops up as her account loads. Another thing is I was trying to upload a user photo (in my user account) and her pictures showed up in my account and I couldn't access mine. Does anyone know why our accounts are meshing? I cannot find anything about it online, and I don't know how to fix this! PLEASE HELP!!

It's probably best not to save anything to the Desktop but to the Downloads Folder under your login name in C:\Users then point all your downloads to that Folder or move them to that Folder after completing the download. Oops, you are logging in to your own account/name or logging her off then you on? Using Switch User may not always help.
