Under Vista, any version, the cursor jumps with some tools and HDMI output is blocked even with program not running. Cursor problem is very noticeable in Caleidoscope and Calligraphics, both unusable. Cursor jumps are also noticed when TuxPaint is not running, or even after uninstall. Video driver or card seem affected. Running in XP mode or under administrative rights have no positive effect.
The same program under native XP runs smoothly
