Well guys, I uninstalled DF and reinstalled to see if it had any effect and it did. I really should have tried that before starting a thread....
Of course the banners and planes are the same size, but my shots are connecting again! And the sloppy aiming problem is corrected as well. My first game after reinstalling was short but I was at 8/2, and next game was 12/5, more typical KDR's for me. Perhaps when there are minor updates within a DF version like there was upon Zuperman's return, it's a good idea to wipe the slate clean and reinstall?
Either way, thank you all for your responses - this little piggy is happy again
PS Davy, I don't understand this credit card charge - who the hell is Ashley Madison? Is she the consultant you hired to fix my tablet?
