Time out issue causes loss of unposted replies

[Crapshoot]

I don't know if this has happened to anyone else or has been posted before. This has happed to me a couple times now. I have been in the middle of posting a reply here or there and either one thing or another here at the house has caused me to get up and diverts my attenion for a bit of time. When I get back to my reply message, once I finish it at click submit I find I have been logged out or timed out. All the stuff i just spent some considerable thought writting has been lost. Is this just my computer or is this a forum function. If its not my system then I would like to suggest that an adjustment be made to the timeout/log out thing that causes the problem. Thank You.

A simple work around for longer post is to create the post in M/S Word and then copy and paste to the forum when ready, also helps me with spell checking.

When this happens to me I've noticed that I the post looks like it has almost been posted and must click the submit button again. I also use Word if I think i'm going to be posting a longer message.
