> This same STAGE.DAT got Prodigy in trouble in the early 1990s when users discovered that it could contain fragments of data culled from their PCs. As it turns out, Prodigy's client was filling in "empty" portions of STAGE.DAT with random snippets of system memory. Users were convinced Prodigy was spying on them, uploading this data to its servers (it wasn't); Prodigy denied this and released a tool for the paranoid to zero out their STAGE.DAT files.
