Copy-Paste Conditions problem
When defining a complex interaction, pasting "Else when" conditions (with or without adding an action) in the Event viewer often seems to cause the conditions to become out of order in the Events viewer, and separated from the associated actions. It is very distressing as you think you have lost your work!
I find, however, that if I cause the viewer to re-paint (by closing and opening it, for example) the order is correctly restored.
.. Just trying to help improve a great product! :)
