if e-mail is moderately long if I delete a letter or digit the cursor disappears, have to recover it, all deleted letters or digits appear at end of e-mail
If I type a moderately long e-mail (I haven't counted the letters/digits to determine how long), then suddenly letters won't appear. If make a typing errors, and backspace over or delete the error/s, the cursor will disappear. It's not anywhere in the body of the e-mail (or anywhere else I've noticed). I can get it to reappear by highlighting every word in the e-mail, then undoing that.
All the letters/digits I've deleted reappear at the end of the e-mail--but only in the e-mail received (by the recipient). If I save the e-mail as a draft, when I look at the draft, the I'll see the deleted letters/symbols at the end of the e-mail. If I click on edit, they disappear. But recipients see all of them, regardless of whether I edit the e-mail or not.
The last time I asked this "question", I was told to update. That was probably 5 updates ago. There has been no change.
I don't know if the problem persists in safe mode because I have forgotten to switch into safe mode every time I use TB. Sometimes I remember to run TB in safe mode but don't have reason to type a long e-mail.
I'm really tired of this problem.
