Marlene,
So that in future we know which version of FH you are using, please use the
Profile link in the heading of the
General Usage Forum on the main Forums page, and enter your
Family Historian version.
Also, with FH V5 you could use the
Ancestral Sources Data Entry Plugin that ensures the current FH Project is opened by AS.
BTW:
It is using
Dropbox because you have chosen to put your
Family Historian Projects folder within the
My Dropbox folder (instead of the default
My Documents folder) presumably so you can preserve your FH
Projects in the Dropbox cloud storage &/or share them with another PC.
