Qt widget not editable except after interacting with the 3d view
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
This bug is not consistent as it only show up once in a while.
Not sure if it is a Qt bug or not, but what is happening sometime is that it is impossible to edit any widget (text field, spinner, …) unless you interact with the 3D view first. (Change of focus)
