That would definitely explain your issue.
Sometimes there are time-out issues on certain forums, I don't know if it happens here or not. One way around that is to type your long post in a text document and then when you want to post it just copy and paste it to the post.
On this forum, I never log out. When I open this forum, I click on "new posts" and see all the new posts since my last visit. So if you visit here often, I wouldn't log out at all, there is no need to.
