Thanks for the report! Unfortunately the log does not contain meaningful information so we need to reproduce. I tried on Windows and both ‘a’ and Enter keys work for me with the Draw effect using the latert trunk. Need to try on Mac.

Draw effect in segment editor works well in 4.8 but not successful every  
time in 4.8.1.

I tried 4.8.1 on mac and still had no problems. Any idea how to reproduce the issue?
