Whenever I upgrade PRTG to a new version it reboots the server when it is done. I would expect it to ask if you want to reboot now or later, not just reboot the server with no warning. Is that how it is supposed to work, or is there something wrong with my installation? Is there a configuration option to change it?
P.S. I think you're going a little overboard with the captcha thing, I've had to do it three times already.
