I usually right-click to go to "Edit" menu so I can add the Contect, Project, etc.

It happened to me sometimes that I click on "Convert to project" and then the task is converted into a project right away (no matter if the task is assigned to a project).

I think there should be a confirmation pop-up when you click there.

I know that you can edit also if you double-click the task, but sometimes my browser window is very small and the task title is very long, so I cannot double click on the task itself.
