Mike Willegal suggested putting a delay in line 30 between checking each paddle. That fixed it!
PS. Why does it work? Mike, Dan R., etc. say paddle cross-talk is the reason why a delay is needed. See the paddle section at http://www.easy68k.com/paulrsm/6502/AAL/AAL8209.TXT. Further discussion in the Apple II Enthusiasts group on Facebook...
