Thanks for doing that test. I cannot think of any reason for the problem that you are having, but if you do happen to solve it, please post the solution so we can know.
As illogical as it sounds - and maybe you have already done this: perhaps uninstalling and re-installing Chrome while at home might fix something. I know Chrome is working at your office, but I'm not sure what else to try. Hopefully you do not have too much customized within Chrome or too many bookmarks, because for the purposes of this experiment, it would be best to check the box for "also delete your browsing data" during the uninstall process.
If you do have Chrome setup with plug-ins and bookmarks, then don't bother with the uninstalling and re-installing test; it is just another straw that I'm grasping at.
