Inconsistent sequencing of Tabs on a Form across multiple Managed Solution installations

Hi folks

I have a CRM 2011 Solution that is installed at multiple customer sites.

I recently added several new Tabs to the Contact form.

In my unmanaged Solution the Tabs appear in the sequence that I want.

When I release the updated Solution in Managed form to our customers the sequencing of the Tabs is not only different to what I have set up in my Unmanaged Solution but inconsistent in the sequencing across the customer installations.

Does anyone know why this might happen?

Thanks

David
