I'm getting the same problem. I am new to construct and trying to start my first project by adding a BG. I am able to add an a tiled BG object, but when I go to add the image from the beginner tutorial, opens the image editor (although it only has a small number of features) I can interact with the window, select an image, rotate it, clear it etc... but I can not return to Construct at all from there. I cannot seem to close the Edit Image window in any way. If I try to interact with construct, ignoring the image editor window, it informs me that an image window is open I need to close it first.
Eventually I have to exit via shutting down with Task Manager.
Have checked all drivers for updates and w are good in that dept.
Any Ideas anyone?
