Error 2032 returned after AIR 3.7?

After the updates on April 10th, our AIR application is giving the same I/O errors from a few years back.

HTTP request error: Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032" errorID=2032].

I noticed in the release notes something about 'sandbox' updates.  This could cause trouble for an older flex app like ours.

Has anyone else seen this behavior?

Here is one of the requests that isn't working:

Top level version info:

xmlns:app="app.*"

xmlns:mx="http://www.adobe.com/2006/mxml"

xmlns:updater="http://updater.readingcompanion.org/"

Function:

private function submitDraftWithRec( event:Object ):void {

            if (event.detail == Alert.YES ) {

                displayFreezePopup("Submitting draft with recordings, please wait... This could take a couple of minutes.");

                var httpSvc:HTTPService = new HTTPService();

                httpSvc.url = BB_WEB_APP_URL + "book/submitDraft";

                httpSvc.method = "POST";

                httpSvc.addEventListener(ResultEvent.RESULT, submitResultHndlr); 

                httpSvc.addEventListener(FaultEvent.FAULT, httpFault);

                httpSvc.send({"bookID":BOOK_ID, "userID":AUTHOR_ID, "withRecordings":true});

            }

        }
