I found a bug in the krypton navigator. To see this, open the explorer krypton, and we went to: Navigator-> Navigator + FloatingWindows.
In the paper 5 and 2 of the floating screen put them side by side to see documents 5 and 2 at a time,

is now floating screen by dragging it to the main screen of the documents would be the 3.4 and 1, fails us, but really the screens are added to the form.

greetings
