Some minor changes have been made to the Action chart settings form.
The Scale field allows you to choose a scale and subscale, such as 'week'/'day', to display the Action chart in weeks, subdivided into days.
The 'Open action' field has been changed to 'New action'. In this field, choose the color of the action selected on the Action chart form when you open that form from the Actions form (from the Action chart field).
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.
