4R8 questions

Okay, I’ve finally gotten around to installing the P2 version and have come across a couple of worrying issues. The first is that when using my wacom tablet, the active point often jumps uncontrollably vertically on screen. Does anyone else find this?
Also it won’t connect with Keyshot. I’m using version 5.3, aren’t they compatible? I might have to go back to using 4R7, although anything I’ve done on 4R8 won’t load on there. Any advice gratefully received.
