I haven't had the text box problem you describe, but if your browser keeps warning you about this site, then you should white-list Wrong Planet in your browser's security section, and in any security extensions you may have added to the browser.
I have several browsers on my Win 7 PC. I had been mostly using Firefox, but a couple of months ago I started using Google Chrome instead. I installed some security and ad blocking extensions, and now I white-list all my usual sites in the security apps. You can do the same thing with the security extensions in all the browsers.
Hope this fixes at least part of your problem.
