selectROI is not working ?

I run this code https://github.com/spmallick/learnopencv/blob/master/MultiObjectTracker/multiTracker.cpp and I am using VS 14 in windows 10 and opencv 3.4.3 . In console "select a ROI and then press space or enter button! cancel the selection process by pressing c button!" I select the object by mouse and then when I press space or enter not working .how to fix that and do next step tracking?
