if a project has a lot of tasks and you open the project in a Gantt in Firefox, there are no vertical scroll bars so you can only see the first 20(ish) task rows and cannot see others.
Is this a known defect?
This does not occur in IE or Chrome
Firefox: Project has 37 tasks - No scroll bar to see other lowers tasks. You have to collapse the summary tasks to see others
CHrome:Same project
