10.9.4 Maverick Upgrade - Issue with multiple monitors

I have just upgraded to Maverick and there seems to be a problem with my second monitor now going to a black screen every time I use the mouse or scroll up and down a page. Is there a fix for this? Any help would be appreciated as it is very annoying.

This is being discussed in a number of threads - unfortunately there is no single thread, but this one is most recent: Second display problem with 10.9.4


(More unfortunately, there is no fix and Apple generally hasn't been giving a scheiß about the issue since it first cropped up in 10.9.3...)
