It's not always due to impatience. I posted a response but after a while I got "Server Error" or "Timed Out" so I posted it again. Then when it got posted the first was there as well, even though I got an error message. I agree that posting 6 or 7 times is a bit much but because of the popularity of the Forum it is a bit frustrating. I now usually leave it for a while and try again later on, by which time, of course, someone else has managed to post a similar answer. But that's life. The answer might be, if you find your post is duplicated, to tick all the dupes as resolved???
