Hi,
First, I cannot reproduce this. When I split a task, it is the finish day
that changes, not the Start date. I hve experimented with some constraints,
but to no avail. I cannot change the start date by splitting a task.
On the other hand, I do not understand you when you say that:
"the starting date has changed and got four 10days.."
A date is a date, not four ten days, so sorry, I fail to see what you mean.
You ask what you should do... IMHO it is much more efficient to handle this
as 4 tasks with FS links and a 5 day lag between them.
Hope this helps,
