Step-time entry - unwanted rests

Please, please try to get step time entries sorted so that unwanted rests do not appear. It's such a shame to have this problem in software which is otherwise so very attractive. It's been over a year now since I tried Notation Software, but I am still having to use my 'previous' program (no names !!) even after a long period of very curtailed musical activity. I'll soon be in my 80th year - I may not have much longer !!!! Best wishes to all.
