I think I see what's happening there. Here's what you can do:
1/ Make sure you have the latest version of ArtRage, 2.5.20 ( Help, Check for updates )
2/ Create a file called no_ink.inf and place it in Artrage's resources subfolder. Any file type will do, only the name is important.
So for example c:\program files(x386)\Ambient Design\ArtRage 2\Resources <-- the file goes here.
Start up ArtRage. Now Artrage will not be using Microsoft's Ink Services, and this should prevent the small 'dot' cursor you're seeing which is standard when using Ink Services. I hope that helps!
