I write to communicate a bug since I updated to macOS Big Sur (11.0.1)

The version of Doit that I'm using is Doit for Mac, Version 4.2.6 (41161026).
The app crashes when I try to move one task to the left pannel, using the mouse,in order to change its context, time, goal, or anything else.

Please fix that as soon as possible.

yours faithfully
