On Windows 7, I noticed that the Dropbox application shortcut took a few seconds to open and all it really does is open up the local folder in Windows Explorer. So I deleted the shortcut and manually added a shortcut to the Dropbox folder; that opens up in a jiffy.
To my surprise, when I looked a few days later, my manually added shortcut was gone and the Dropbox application short cut was back in the same position. Ok whatever, I may have imagined things so I did it again. Sure enough, it happened again.
Any idea what is going on here? How can a shortcut silently get replaced like this? Who/what is doing this?
