[SOLVED] Problem with double jquery library calls / "Shopp" plugin

First, I have to say that I only partially understand what's happening with "jquery library calls".

1) Apparently Atahualpa, in its header.php file "calls" ("loads"?) a jquery library -- something to do with being able to execute javascript.

2) I was having some un-related trouble and the admin/inhouse support folks at the Gravity Forms plugin discovered that the Shopp plugin, that I also have activated on the site, was, in its header.php, ALSO calling a jquery library (a different "version" of the library than ATA was calling).

3) I did some searching around here in the ATA Forum and found a few instances where people were having "jquery library" issues.

4) Would it be possible to have the option to have ATA NOT make the jquery call? Can anyone (Flynn??) explain what's happening with the pros and cons of different solutions ...if solutions ARE necessary.

I remain happilly ignorant, Jim
