Attention pop up is annoying.

[IkoIko]

With customer Invoice open, and clicking Preview Invoice, the following popup appears...

"ATTENTION!
Any changes you save to this invoice will be seen in all subsequent invoices!"
Even if there were no changes made, just clicking Preview the invoice, calls up the popup. The invoice contains recurring items.

That is expected if you are saving an invoice in status "Recur". It is an effort to keep folks from sending the invoice in that status out as a "real" one when it is really just a template for future use.

I'm making it better - I know it is a bit bizarre in the way it works right now!
