I have heard from other zz9000 users that after the 3.1.2 upgrade that screen dragging started working. I have not had the same success after upgrading to 3.1.2.
I asked to see the ToolType settings in their zz9000 monitor file to compare to mine and everything seems the same except I noticed that they did not have SOFTSPRITE ON. I did a complete uninstall and reinstall of 3.1.2 and if I don't turn SOFTSPRITE ON I can't see my mouse pointer move. Not sure if that softsprite has anything to do with why my screen dragging is not working but I thought I would mention it as a potential clue.
Thank you for the help and thanks for continuing to develop P96!
