As the title says. If a thread is long then the later posts do not have syntax highlighting on the code in the newest posts.
An example,
https://vexforum.com/t/sprocket-and-chain/14951/1
Early posts have syntax highlight, scroll down a while so the page has to reload more and highlighting does not work.
James,
Thanks for bringing this to our attention. The syntax highlighting script was only highlighting the code that was on a page when it initially loaded, it did not account for more posts being loaded later. We have already pushed out a fix, and this problem should be solved.
As always, let us know if you run across any other potential issues.
