Well this question and this question are similar but no answers that work. In fact I was hoping WindowStartupLocation=CenterOwner would work...it doesn\'t. It seems to cent
I had the same problem...but it was mostly due to the fact that, when i wanted to get rid of the child window, I used hide() instead of close() ... so when you reopen it, because it was hidden and not closed, when the parent window is moved, it still opens at it's startup location...
So when close the child window instead of hiding it for example when finished working with it.
