Trouble is I've never seen this ACP, although I am dubious whether anything useful will be in there for this sort of thing. Another problem with IPB is the license, even the theme requires one, which means I can't look at the code.
I have to be honest though, if it's really that much of a problem for anybody hopefully they like one of the other themes. I'll certainly trial them.
The difference in the link is "pid" versus "gopid", the latter appears to be the correct object. It's strange that I never noticed how the page automatically scrolls after submitting a post. What is more strange is that the fragment identifier is not even in the link, the PHP deals with "gopid" accordingly.
Therefore, all that needs changing is "pid", it should be good after that. The "Show the link to this post" should also be edited to reflect this (here, "p" needs changing to "gopid").
This isn't actually how it is in the other themes, the <a name="entry$pid] is still created,. For whatever reason it doesn't appear in the Deep Blue theme, but with "gopid" it will still scroll, how is beyond me but I won't complain.
