This was a bug, arising only when a character was deleted via the 
command line. It has now been fixed. The new version is available both 
in the main installation files (delt32.exe and intk32.exe) and in the 
'test' directory (intk32t.exe).

This version also makes the 'Multiple images' option available from the 
'Information' dialog, and corrects problems with output files and with 
accessing NT servers over the Net.

The recommended way to delete a character is to select _no_ states - 
that is, deselect the ones you have already used. This is described in 
the help for the 'Restart identification' button:

    If, at any stage, you think you have made a mistake and want to
    correct it, click on the appropriate character in the ‘Used
    Characters’ (bottom-left) pane. The program again displays the box
    for selecting character states or entering values, and you can
    change the information you previously entered. You can remove the
    character from the identification by clearing all the information.
