Talking of the PC ver 4 Engine DJ under W10, the software loads, yet it not visible as a window, normally this thens to be a window openning with 0,0 dimentions or out of screen.
Anyone know how to “reset” the coordinates?
Removal and reinstalled hasnt helped.
Try this: hold shift and rightclick the icon in the taskbar. Press maximize or restore. I think that resolves it. If not, press move. Then one of your keyboard cursor keys. I think you can now drag the window in screen again by moving the mouse. Does this help?
Thank you the SHIFT maximise worked.
Good! 
Glad to read you could resolve it.
