Hello kissson.
I can't reproduce this behavior.
With a command line like "ChromeLKL.exe google.hk", Google Chrome 17 opens this link in the last active Chrome windows.
Do you have some extensions ?
For tests:
Rename
(or Backup and remove) your folder
\Apps\Chrome and
re-install it from the catalog. (valid the prompt "Google Chrome is already installed on your LiberKey.Do you want to re-install this application ?")
Does it have the same problem ?
