The links aren't the problem, but the rule of thumb is to select and copy the post before hitting "submit message." Sometimes you can use the back arrow to retrieve the post, but another rule of thumb seems to be that the more work you put into the post, the less likely that is to work. :-/

Copy the post and open the thread in a completely new window, don't try to resubmit in the same window. It usually works from a new window or tab and you can paste what you saved into the dialog box.
