The latest 5800 firmware (version 40.0.005) introduced kinetic scrolling in some parts of the OS. This has caused the following bug. When using ChoiceGroup.POPUP to display a selection list within a Form and the user selects an item by tapping, the JVM crashes. More specifically, when the user taps and holds on the selected item, the item's colour is highlighted by turning from red to grey. When the user releases his/her tap, the JVM crashes. A workaround is for the user, while keeping the screen pressed, to move slightly up or down until the selected item turns red. Then it is safe to release the pressure from the screen and the JVM continues. This bug was not present in earlier firmware versions.
