Support has to turn them of via a dbase script as we didn't add a preference yet for users to do it. To date we've updated thousands of practices and we've received 3 phone calls to turn them off. If we were to receive a large number of requests we will add a user preference but we felt that most users would have a perception similar to Qaiser's recognizing it's not intrusive to workflow so what's the harm, and maybe you gain a little knowledge in the process.
Having an ad that is not AC related would be the problem. If the "ads" are more like tips in using AC, then that is much different. This just feels like a gateway to eventually have 3rd party ads in the product since the whole user base that wants to continue to ePrescribe has to upgrade (or pay $0.01 per Rxn per the recent AC communication). Thus, generating easy profit for the company and the users get no discount on maintenance fees. 3rd party ads could be a source of security risk. That should be a big concern for any medical practice. I am completely against ads in a product I pay money to own/use.
