That single line of text you just typed in there, dear sir, is the worst pile of bullshit I've ever read.
What do you mean by that it "mangles" the numbers? I've been using chrome to launch AoS for around 2 years, and I've never experienced anything alike what you are describing.
By "numbers", I suppose you mean the SIDs. If that is the case, then I can't see how chrome is supposed to "mangle" them.
Listen, what Chrome, Firefox, IE, and pretty much all other browsers do when they encounter a non-standard URI, is that they search through the windows registry for a registered URI matching the one passed to the browser, and then if they find one, they will read a specific registry key which contains a program to run, and run it in the shell with the parameters specified by the registry key.
I obviously fail to understand how any of the above routines can affect the number in the URI. If you feel that I've forgot something important, or disagree, then please let me know.
