This has been bothering me for ages. Would somebody mind visiting the above web site, clicking the heading for a news article with at least several comments, then scrolling down to those comments and clicking Reply on a few of them? What's supposed to happen is that the comments form that normally appears at the end of the comments jumps up and appears indented under the Reply button. I assume it works normally for you? Here, at most, the page scrolls a little but the form never appears. The bigger problem is that this happens with every browser on this Windows 7 PC, not just Firefox, suggesting that a script or something is being blocked system-wide...but that doesn't appear to be the case. Launching Firefox's debug tools, all requested files either load (i.e. show a byte count) or list "cached". Opera Mini, running in the MicroEmulator Java console does work, BTW. I often block domains in the HOSTS file, but switch this off during testing, and it makes no difference. There is actually no antivirus or other software currently installed, but I do run MalWareBytes manually sometimes. I am not looking for interactive problem-solving, as I'm very tech savvy and that's likely beyond the scope of this site anyway. I was hoping, though, that somebody more savvy with Javascript would take a quick look at the code and note the script files involved. I see most of the processing is in comment-reply.js. I used to be fair with Javascript but haven't touched it in nearly 10 years, and am still understanding IDE-style debugging. Thanks for any suggestions.
