Why can more than one student open my Kidspiration document at the same time?
This is probably happening because the file they are trying to open is a plain Kidspiration file. In order for more than one person to open a Kidspiration file, it must be a Kidspiration Activity file. To create an Activity, please open a Kidspiration file and choose “Save With Activity Wizard” from the enabled Teacher menu. Once the Activity is saved, it will be in a format that automatically creates a copy of itself when the students try to open it.
The difference between a regular Kidspiration file and an Activity is one of placement, rather than file type. Any Kidspiration file that is placed inside the categories in the Kidspiration Activities folder will be considered an Activity by Kidspiration (it will be available in the Activities sections from the starter screen). Files that are considered Activities can be opened by more than one user at a time, as Kidspiration is simply making a copy of the file before letting the user use it. Once a file is moved out of the Kidspiration Activities folder, it is considered a regular Kidspiration file and cannot be opened by more than one person at a time. With all of that in mind – what some people choose to do is to save the file they wish to use as an Activity to somewhere easily accessible, then place it in a locked folder on the server. When others want to use that file as an Activity, they can copy it to their own machines before using it.
