The Editor is also not working for me in version 5.7.0. Initially if I open any test step in the editor window, the editor does open. But if I then minimize that same window, and then click in the tree or click on the test step (in the test case window) to bring the window back in the editor, then the Editor does not open, and the minimized tab for that window eventually disappears. This happens with any test step regardless of type. It happens for test cases and test suites as well. Any window that is minimized must be opened with the icons in the right hand corner of the window Clicking on the tree or in the list of steps does not work now.
