Would it be possible to move (or duplicate) the button "Post Quick Reply" so that it is up next to the "Reply to Thread" button?
That way at least the user would be more likely to click that button to post their comments rather than clicking the "Reply to Thread" button by mistake a second time.

I assume you (Lester) are indicating that this Forum software is a canned software that, each time updates come out, would require you to re-patch the code.
Possibly, if that is the case, it would be better to forward this thread to the owner of the Forum code so they could include the "Fix" to the code directly.

It really is heartbreaking to spend some time replying to a post with techincal details, re-writing you comments to make them more clear, etc. etc. to then find that all your thought just evaporated into thin air.
