Inconsistent operation

Have DraftSight standard. Some commands functioning inconsistently and program crashes a lot. Sometimes the hatch and insertblock commands will cause the program to freeze. I see the command entered on the command line but the program hangs. I have to hit ESC key to continue. Sometimes the commands operate normally. Sometimes the program will accept fractional values and sometimes not. In paperspace the program tends to crash a lot when I move paper around holding down the roller wheel on mouse. Never had these issues with the free version:(
