Folder Views

This is really starting to get on my t**s now.
My folder views keep changing themselves and its really annoying me. When I open My Documents from the start menu the view is "Tiles" like I want, but when I open it from My Computer it is in "Thumbnails" A few folders are like this.

I have changed the settings from right clicking in the window and using the drop down, I have changed it in Edit>View and I have changed it in folder options under Tools. Still it changes back, but only when I open it from My Computer....

Any ideas??
