Google's Chrome browse using a sandboxing technology which is not
currently compatible with ThinApp (which also provides sandboxing)
http://dev.chromium.org/developers/design-documents/sandbox
You found you can disable Chrome's sandboxing mechanism using
"--no-sandbox" command-line parameter and then it works under ThinApp.
To do this, add your Chrome icon onto your MetriQ folder. Right click the Icon and choose Property Sheet. Into the Aruguments field type
"--no-sandbox" (without the quotes). Voila!
