When Intersection Magic updates are sent to users, the 'custom configuration' that was sent for the first install is not included with the update cd or diskettes. The result is that, for a network install, no data directory (containing imwuser.exe) is created, and thus the 'client' side of the install can not take place. For a local install, only the demo/tutorial is installed, there is not IMW icon or DATA directory.
Whenever Pd' Programming changes the Intersection Magic database structure, the program automatically "knows" to update the database and its indexes. In a couple of situations, the program prompts the user to update the indexes and then doesn't seem satisfied, requiring it over and over again.
