On occasions the emails I send to groups are corrupted by what appears to be some editing controls that should be hidden. There are no signs of these in the emails I send out but they appear in the recipient emails. I have also experienced the same problem with emails I received. I use Yahoo Mail most of the time. I often use Word to draft out the email then copy it to Yahoo. This is a problem that has only arisen recently although I have been sending emails for years. And it is intermittent so I have been unable to discern the circumstances under which it occurs.
