G-mail troubleshooting

[Joe Busuttil]

When I type a reply to a message in G-mail, sometimes the text vanishes without my having hit the delete button. Why this happens, I just don't know!
Have tried to access my reply by going to DRAFTS but there I only find the first line of my reply. The rest of the reply does not appear anywhere.!

Have also tried DRAFTS on other occasions, only to find that not even the first line of my reply appears!

Have also tried TRASH and SPAM, as sometimes the unfinished reply is
automatically filed there. Again to no avail.

Plse help as my head is spinning from many vain attempts to retrieve my texts.

Many thanks.

Joe
