All I wanted was for Supermium to open internet shortcuts - that is, respond to http and https links. I made these changes to my registry (in XP 32-bit) and that solved the problem. It also sets the default icon for new shortcuts to Supermium

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\http\DefaultIcon]
@="C:\\Program Files\\Supermium\\chrome.exe,0"


[HKEY_CLASSES_ROOT\http\shell\open\command]
@="\"C:\\Program Files\\Supermium\\chrome.exe\" --single-argument %1"


[HKEY_CLASSES_ROOT\https\DefaultIcon]
@="C:\\Program Files\\Supermium\\chrome.exe,0"


[HKEY_CLASSES_ROOT\https\shell\open\command]
@="\"C:\\Program Files\\Supermium\\chrome.exe\" --single-argument %1"
