Although I’ve been using the new simulator more in RW8 and haven’t seen those problems in the simulator or preview when I do use it.  
Is it happening on all projects or just one?  
Might take a look at this post:

I have a two page (placeholder) [site](http://www.sibeliususers.org) where moving to Preview from Edit doesn’t always display the right page. A Preview can take anything up to five minutes to generate. Anyone any ideas, please?
