Hmmm... ?
As I posted above...
- "And, can you check to make certain that your files that contain the 'hash data' are not being deleted for some reason or possibly being saved in an incorrect folder ?" -
There is definitely a problem.
The hashing should take place only once unless there is some alteration made on a file, or possibly the 'location' of a file is changed.
You must be having a problem with the hash data file not being saved in the correct place... or
LW is, for some reason, not 'looking' in the correct place... or
The hash data file is being deleted for some reason, on shutdown or launch... or
The file is somehow being 'mislabeled'... or
Or, what ?
