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.

3

Enter and ‘a’ both work for me with 4.8 Draw effect in Segment Editor on mac.

4

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

5

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