Blimey... It looks like you've caught a transition widget half-way though a transition. (If you click the layers button in the preview pane repeatedly the wobbly effect when the layers panel shows up is a transition widget).
Obviously, that's not supposed to happen!
Are you using the Full version or Free version of ArtRage? If you go to the help menu, and select 'About ArtRage' what version is it?
Regarding the tablet problem: Inside ArtRage do you have the 'mouse mode' preference enabled? (See attached picture).
