The GreatWaloo I think you may be on to something because I also have noticed, when running the Chrome Browser, that I only get the Captcha nonsense, whereas with Safari on my phone, I get the full imaging test nonsense. There is a big difference in the level of nonsense between merely getting Captcha and instead getting the dreaded Imaging Tests. I am not sure everyone here is even understanding this point unless they have been subjected to it.
Being logged out has nothing to do with it because I am logged in. The Canadian posters here are not understanding that before you ever get to the log in, you get Captcha/Images and then, once you pass, you are automatically logged in as per usual. Captcha is not logging anyone out, it is simply a roadblock thrown in your direction when you click on MERB in your favorite places.
