Build 3570 and Sample Tank 4

I am running Cantabile 3 build 3570. I just installed IK Multimedia Sample Tank 4 MAX.
ST4 runs fine as stand alone however when I run it from Cantabile it does not display correctly.
It’s hard to explain but certain elements do not show and when pointing with the mouse and clicking it is not clicking the correct element on screen.
All my other plug ins work fine and I know ST4 is fairly new.

Any thoughts?
