Hi, Jim:
I just tried to replicate the issue mentioned in your second paragraph, where I open a form from DAT, switch to design view, add the fields from the GetMyInfo service to my form, save, close, save DAT, and open the form again... and the fields I've added do show.
I'm using XP, and my form is published locally. Can you tell me more about how you have things configured? Is your form published locally? Which version of DBXL have you installed - v2.1 or the beta v2.2?
For task 3 1.D in the Getting Started for v2.1, you can just browse to the location where you published your form earlier if it is different from the location in the tutorial. For task 3 1.D in the Getting Started from v2.2, again, you can simply browse to your form if it is located somewhere other than the suggested tutorial location.
