I've got a simple About box which displays the current version and date, etc. of the application (custom widget!). It's a modal dialog which is brought up by a microflow called when the About menu item in the navigator is selected. There are no objects or data attached to the form; it's just a table with two cells. In one of them there is a button connected to a microflow. All this microflow contains is a "close form" activity, so that the user can dismiss the About dialog. When you click on the button nothing happens. Why won't the dialog close?
It seems to be a bug and is reported. I'll notify in this thread if fixed*
