P4W change start date

[AllDuf]

Hi,

I try to change the start date of a task and when I select the desired date, P4W automatically sets it to another date. At first you might think that there are constraints and dependencies, but this is not the case according to the information window of the task.

Am I missing something here. I have a lot of experience with Ms project pro but this P4W is diving me crasy.

Funny to say, I just found the solution. This issue was at 10 inches in the front the screen. There was a constraint with a sum task. I have to get more familiar with this new user expérience interface.
