I have created an application that opens a modal window created with the UserEdit class, which I attach below, by the following code that I put on my launcher class (primary stage):

UserEdit userBox = new UserEdit(stage);
userBox.start(new Stage());

when I try to close that window, it reopens again automatically. This code works fine with JavaFX 2.0 build 36. This issue only occurs with JavaFX 2.0 build 37.
