I don't know if it's a bug or a feature, but I will ask the following:
If I am in a grid view of the calender module (e.g. week or month view), it is possible to move an public, read-only event from another user - so that the day or/and the time of this event has changed. So it's possible, that someone changes someone elses events, although he shouldn't be allowed to.
If I am in the details view for a public, read-only event it is not possible to change anything.
I would prefer, that the moving of public, read-only event would be not be possible.
Thank you for an answer....
Markus
