Not sure where we should enter bugs now? Hope it's ok to do it here.
When we move a task from one project to another project it moves ALL the time entries for ALL the tasks in the original project.
Example: Project for creating a large multi page document. Has around 15 tasks. One task needed to be moved to a new project in order for the time applied to that task to be moved. New project was created. Task was moved to the project. All tasks in the original project against all tasks were moved to the new project ie. no tasks were left in the original project.
