I had a problem in the old format that occurred about 20% of the time, so I assumed it was something on my end- using Vista with Chrome's browser.

When replying to a post, if I chose "preview post", about 1 time in 5 the page I was replying on would simply hang there, or sometimes go to a page that said "Page not available". Clicking the back button would bring me back to the original post, meaning all those replies would simply evaporate.

[Pauses here in order to let the chorus of "Maybe that's a good thing." die down...]

In SRP v2, I've not had that problem once. Previews "preview" correctly every time. Works like it should.

So, if you knew about that and fixed it, thanks! If you didn't know about it and the problem just went away by itself, take credit for it anyway.
