What controls dependencies to be red or black, se picture
Tasks connected by red dependencies are on the "critical path". A task on the critical path directly influences the overall project length. If the task is late or extended, the project will be late or extended.
But I wish to hide "critical path"... ?
To hide the critical path, click Show Gantt Pro > Default Options and un-check the option for "Show the critical path in Gantt chart".
Thank´s a lot :-)
