SUMMARY

When ordering icons in the task manager widget, the wrong icon is selected and reordered. This appears to affect the second and further applications which are selected and reordered, until the application focus changes. Changing focus appears to reset this condition. Until the application focus changes, whenever you try to reorder applications in the Task Manager, only the first application selected can be reordered.

STEPS TO REPRODUCE
1.  Drag an icon to reorder it in the Task Manager
2. Without changing focus, attempt to drag another icon to reorder it
3. Repeat.
4. Note that changing focus to another application or widget and back will reset and allow the correct application to be reordered.

OBSERVED RESULT
Reordering multiple applications in the Task Manager is confusing and does not work as expected.
