#1782:

• Changed tooltip generation in ProblemInstanceConsumerViewGeneric (typeof(T).Name doesn't work, because T doesn't change miraculously when the selected provider changes). The current solution might not be optimal, maybe include another property "FileFormat" in IProblemInstanceProvider that can then be TSPLIB, QAPLIB, CSV, etc.
• Set instances combobox to not display a selected instance initially and disabled button in this case. If that still doesn't reduce the confusion, then I think we have to add problem loading on selected index change and do away with the button.
