A family of Microsoft relational database management systems designed for ease of use.
I'm having the same problem as Unis_954.
All tasks are auto-scheduled, my resources are working at 85% and 70% respectively and I can have it completely resolved of conflict. When I save and re-open I get the scheduling error for all remaining work, when NOTHING has changed. I spend hours "tricking" project to resolve it, usually by moving the tasks to unallocated then reallocating them, but whenever I resolve it, on reopening the same thing happens again. I'm getting this in 2013, and also when I save as 2007 (my colleague is using 2007) and the same thing happens in both. It's driving me crazy - I spend all day resolving something that has no issue? I'd just ignore it but I can't as if there is a genuine error I won't see it.
