I know I've got lost in "too many windows open" and I'll mess up or forget to hit post. What I do now JUST IN CASE is I lose a window or something goes buggy in the upload topic.
Honestly, I haven't had a forum problem plosing posts, so far I can blame them all on me - hope it gets better for you and I hope we hear from others if they have issues. I hope not, but it's good to know of a problem if one exists.
