I'm not a big DBPro user and I have the same problem with the latest version too.
My DBP projects folder is in My Documents folder but when I use Open, it defaults to the same directory as jayell leedham.
I remember a post a while back showing how to edit a DBP text file somewhere to change the default projects folder path, but I can't remember what it was or where the thread was.
[Edit] Just had another look and found it first time! Doh!
Locate the file Launch.cfg in the DBP main directory and open it in Notepad.
Locate the line that starts with Projects= and edit it to show the folder where your projects folder is located. Mine is now set to:
Projects=C:My DocumentsDBP Projects
and it's now working as it should.
[Edit 2] Oops - it isn't. If I double-click a .dbpro file DBP loads but the source window is empty.
