Wacom loses sensitivity in Spotlight (Zbrush 4R2)

hi,

i have Wacom intuos3 and Windows 7 64 bit.
i just installed ZB 4R2 and started texturing with Spotlight. i noticed that every once in a while, like after i saved the tool or imported a new image, Wacom loses its sensitivity for a few moment (from a minute to even five, or possibly until i save again or something). which, instead if nice blending of textures, i get a sharp edge on what i “paint” on my model.

has anyone encountered this? what can i do to fix it?
