When add direct invoice working with Chrome navigator the browser auto reload and says:

Direct Sales Invoice
This edit session has been abandoned by opening sales document in another browser tab. You cannot edit more than one sales document at once.

This  not happens really, no have other  browsers open.

This not happens with Firefox. This browser work well and I can make the invoice o.k. no problems.

the Chrome is not appropriate or something else? I´ve clean the cache but the behavior persist
