In general, Validate doesn't tell the user what it changed. Its messages are vague to the point of uselessness. Today I got this one:
QDF:
Validating your data.
Repaired your data file by removing a damaged category. Please check your category list for missing categories by going to Tools>Category List.
Which category was removed? I have no idea. I searched for uncategorized transactions and found none.
Please, when Validate changes something, provide the information to the user.
