(14/Sep/2001)

Code modifications were made only in the PRZM shell but were not necessary for WinPRZM itself:

Fixed several problems with the compound database.
Fixed the problem of wrongly create input files for multiple application scenarios and crops with two cropping seasons per year (carrots and cabbage).
Fixed problem of deactivated "application" and "write" button found under special scenario conditions.
Fixed problem of inconsistent application rate between shell, grapher and PRZM input files.
Added feature: "Scenario Manager".
Some minor re-coding in order to keep code compatible with the development of the PRZM surface water shell and the PRZM EPA shell (EXPRESS).
