While attempting to read several of the Kantai Collection doujinshi I get a potato at least once on every page! Some pages have to be reloaded 3 or 4 times! I have tried all the different image servers, same issue.
Also, this is the only web site (including other manga reader sites) that causes my computer to just seize up for several minutes at a time! It comes to a dead halt, nothing can break it out of the seizure! Something is running the hard drive constantly while on your site.
