@Louis Li, Deleting Tasks Rated 5 out of 5 stars

*Left* klick the task, then *left* klick the carbage can. It's at the right side of the task's name. Task is deleted afterwards.

A right klick opens the tasks details as well, but the context menu shows text and cliboard options only. Which may be (and in your case indeed was) irritating.
