It seems that you are right, very strange indeed. In previous version I remember that an error message would pop up if there was no control to park on and the task would exit.
On the other hand, changing the checkbox does not trigger the Variable Change or Control events, so nothing would happen (fortunately).

Onderwerp: [BugReports] XPA3.2-Bug: When the only control on the screen is a checkbox, the Modifable and Allow Parking properties are ignored
We have a screen with only one control, a checkbox. We would have this situation most commonly on a subform, but you can duplicate it in a stand alone program.
Create a new task with a Logical virtual, and put in on the screen as a checkbox Change the Modifiable and/or Allow Parking properties to False.
Run the program. You can park and change the checkbox variable. If we had a Column variable behind the check box instead of a Virtual variable, you would actually be changing the data in the database (not good).
