I'm testing OpenERP 7 Project and i do not understand how can i use the Gantt view (Project/Task > gantt) :
This gantt show all tasks (of project task or selection) in the single view without scaling options (i do not find anything). So with several tasks and/or pojects the gantt became wide (very wide) : you can of course scroll in the navigator but you do not see the label, so you don't know what you see...
I also find to way to print the gantt : it was an important document for meeting...
OpenERP has many nice option and data for project management but Gantt view seems to be not useful in real world, but i probably miss something, i'm a novice.
Did you figure this out? I am having a similar problem. I can view a perfect Gantt chart for ONE project, but Gantt view of all project shows just a list of projects with one block for the start date. Frustrating.
