I contacted people who told me if they alt tabbed in adocument using Adobe with JAWS 16-7, that everything freezes.
So I contacted F S.
I was told that Adobe works perfectly; simply do not ever alt tab.
I realize what I was hearing was an off-the-cuff minority opinion.
This issue has been a known issue since last summer and involves 2 of the latest versions of JAWS.
I like the product and most of the people at F S.
