Flash is Dropping Passed URL.field Info

["bkspeck" <webforumsuser@xxxxxxxxxxxxxx>]

Hello.
   
 We are experiencing random instances of the ColdFusion/Flash form dropping the 
passed url.field information.  It is only happening at ONE client's site, and 
only on three computers.  It is a random occurrence, where the Flash form will 
load properly with the ?RecordID=12345 being passed to the form and underlying 
CFC query.  When the form is filled out, and the Submit button is clicked, the 
page seems to reload/refresh without the ?RecordID=12345 at the end of the URL. 
 The record then gets passed to the MS SQL database without the Key Field ID 
number from the URL.  The record is added, but with a NULL value inserted into 
our related ID field.
   
 We thought it might be McAfee Security somehow affecting Flash, but the third 
computer is running Norton 360.  There are plans to consolidate all the 
computers onto a Corporate AntiVirus product (possibly Panda) in the future.  
In the meantime, we've been unable to isolate and consistently reproduce this 
issue.
   
 Has anyone seen this happen before?  Thanks in advance!
