Cubase 6.5 Waves Graphic Window blanks Out

Using Windows 7, 16GB system 3gz. Running 32 bit Cubase with 32 bit plug ins on a 64 bit computer. When using 15 + Waves plugins the graphic displays starts blanking out on the next plug in loaded (Only happens on Waves)

Need clever bod to point me in the right direction?

Maybe jbridge?
