My problem with the Waves plugins has been resolved (both X1 and X2 would crash if I closed a plugin's popup window.)
The solution was to uninstall and reinstall all the Microsoft C++ Redistributable libraries (2005 through 2012) and update the graphics driver on my Lenovo T500.
I am able to now use the plugs in X1 and X2.
Not sure if this new behavior, but X2 kinda freaks out when creating a new project. Right-clicking doesn't work and the screen doesn't refresh properly. Switching screensets seems to fix the issue. Looking forward to X2b....
