One could also make a small tweak to the original post if one were so inclined... again, as a workaround.
No, that doesn't work.
The problem is eHam thinks you made a post somewhere within the last 120 seconds. Even if it is a different post, doesn't matter. It stops your entirely new post.
Then, when you wait on the back window, and try to repost after 2 minutes, it says "you already made a post and this is a duplicate". This happens even if I make a whole new post in the clicked "back" window.
A shorter timer might work, because that would stop the initial freeze.
It looks like Mike sees the issue and has changed something.
