quatprot.htm (Hide subunits on HIV protease makes a ribbon appear instead of going back to previous structure. But that's what Reusch's code specified. Inhibitor off doesn't work on HIV protease; the bound inhibitor remains. Hide active site adds extra structure, based on what Reusch's code specified.)
allenexp.htm (problem with allene.pdb file gives one missing double bond plus one C-H bond that's thinner than others. Use the corrected version I saved.)
examp1.htm (Allenes have missing entries in connection table that makes some bonds look nearly invisible they are so thin.)
