Works fine for a few tasks (up to around 40 in my repeated experience with several projects) and then arbitrarily resets dates to the date the overall project started for ALL subsequent tasks after you hit that magic number. This occurs whether you have a baseline or not, and gives the same project start date as both start and end date for EVERY subsequent task. So it's NOT much of a replacement for M$ Project, unfortunately. Help is minimal at the Serena site.

The download (from sourceforge.net) seems to have disappeared. All of the mirrors are not working even for other (non-mac) versions of the project.

Why is this free? This is a great app for someone that is used to MS Proj - it just works like it should. Only used it a bit - but all seems great and clean - very nice job.
