So you were periodically hitting from same IP to sedo servers? I do not suggest that. BTW why do you want to capture screenshots?
Yeah, apparently that was a bad idea. It locked up on me again and I had to let my dynamic IP change again.
The purpose for screenshots is really to make sure I actually did something with my domains, like parked them, or made websites, or redirection. I've found sometimes that a domain I bought six months ago is still pointed to the registrar or that I let one drop by mistake and someone else has it now.
In other words, a quick script that grabs a visual verification is a quick and easy way to be sure when one has so many it is hard to keep up.
