Why is Eclipse's HTML viewer randomly showing previous output and an error?

Well, this video shows my problem best : http://www.youtube.com/watch?v=yDeChV254Ck&feature=youtu.be

If I have a page that is proper/ok, everything works fine and as expected.

If I purposely induce an error (which I have been doing loads of whilst learning!), Eclipse doesn't show an error at all inline/red underline, and, when I try to run, it will either display an error (which I expect it should be doing every time), or it will randomly display the last successful build.

I can (remotely) understand the logic of alternating, maybe someone would want to see the previous output, but, this is just completely random - no logic at all, so, I just don't understand why it is happening.

Does anyone know what is going on?

edit - been able to recreate this on a brand new install. What is going on!?
