Just wanted to add my observations here, I've noticed similar problems with the graph editors, if you drag a key in the animation palette the window doesn't expand smoothly and just will not show the last couple of frames until you move the scroll bar, this was never a problem in P6 and did not seem to get addressed in SR1.
 
I concur with Ricky_Java 
 
"Notice that the text box in the upper right corner of the Graph window is empty, whereas it should list the currently-selected Parameter, as it did in previous versions of Poser. I can populate the textbox from the drop-down list, but it no longer auto-populates from selections made in the Parameter window. I have to click the right-arrow and select Graph..."
 
I've also noticed that the graphs suffer from a slight opacity, that is to say that clicking in one can sometimes select something in the window beneath, this is also true of the workspace window, I had my toolbar partly hidden beneath the main window and whilst selecting an item suddenly found the translate tool swapped for the break chains tool! Very nearly a disaster!

Incidentally and a little off topic but since Ockham started this thread I've had numerous problems trying to run python scripts in P7 so still use P6 when I want to run any of his great freebies, Jiggles, Smoother and the really useful 2 and 3 graph windows
