I'm experiencing an issue with ArtRage when trying to use the my tablet to control any of the interface controls.
Basically, if I use the tablet to use any of the interface controls that involves the equivalent of a click-n-hold, I have to press with the tablet, hold, wait for the "loading" circle to draw and disappear, then I can move my pen. It takes about 4 seconds for the loading to stop.
For example, if I want to re-size my tool, I press, wait 4 seconds, then I can move the pen to re-size. It also happens when moving a palette.
If I attempt to move the pen before the "loading" circle disappears I'll end up performing a different function, such as panning the canvas or hiding the interface. Very annoying.
I don't have the same problem when using the mouse and as a result I'll frequently drop my pen and use the mouse just to re-size the tool, then pick up the pen again. Very frustrating.
I'm using the latest version of ArtRage (full version) and I'm running Vista 64. I don't experience any slowness when drawing on the canvas. I can confirm a spike in CPU usage when using the pen on a control, the equivalent of what I see when using the pen to draw.
