Don't click the link(supposedly to something on ebay) in the "CREE XR-E P4 bike light" thread, posted under username joelw135. Probably best not to open that post at all. When I clicked the link, it locked up my computer, & I had to shut it off to get free. When restarted, my computer showed a strong warning from my antivirus about "Trojan Horse" something or other. And now, my Windows toolbar at the top of the screen is gone. Admins, it's your call, but I think it might be best to delete that post.
Now if I can figure out how to get my toolbar up again- I need my "Favorites" list back!
