The following changes have been made to the Action chart form:
In previous releases, all rows had a fixed height. In Isah 4.5.2, this is no longer the case. The row height now depends on the number of rows displayed. The maximum number of rows is set on the Action chart settings form. In the Action chart, you can use and on the vertical scroll bar to the left of the calendar to increase or decrease the number of rows.
A calendar now appears on the right. Days with appointments are displayed in bold.
Coinciding appointments are now displayed underneath each other instead of on top of or next to each other.
It is no longer possible to differentiate hour types in the calendar. In previous releases, you could assign different colors to the different hour types on the Notifications tab of the Working hour types form. This tab is no longer available.
Scheduled actions can be dragged to another date.
The Action chart settings form can be opened either from the View menu or from the right-click menu.
When you enter or change an action on the Actions form, the change is immediately visible on the Action chart form. You open the form in the Action chart field. You can change the other actions in the Action chart you have opened in this way. When you click the OK button, the other actions are applied. The action you have changed on the Actions form will not be applied, however, until you have saved the data on the Actions form by clicking the button.
