Windows NT remembers the size and location of the last 28 windows closed.
Each Windows size and location is stored as a subkey at:
The first window for the first user is 0, the second windows is 1, etc. After 28, a subkey is overwritten. The association of these subkeys with a window is stored at:
If your StreamMRU settings become cross linked, the size and location of a window will be stored on top of another windows entry.
To correct this problem, delete all the subkeys of the Stream key and all the value names
of the StreamMRU key, except MRUList.
