The Edit pulldown contains menu options which are used to modify the calendar.
The General preference pulldown allows you to select the default directory for the calendar files and also whether you want to automatically resume editing the last calendar when the program opens.
The two buttons in the lower left corner marked Associate and Unassociate are used to set up and take away a file association for the .wcal programs. A file association is the Microsoft Windows construct when tells what happens when you double click a file. Pressing the Associate button tells Windows that when you double click a file ending in .wcal, it should use Bob's Web Calendar program to open the file. Pressing the Unassociate button removes this association and double clicking the a .wcal file will no longer cause the program to be opened.
