Hi Don, this is for you.
Recently I found that many of the UI buttons on your site don't work anymore. This includes the Discussion and Add to Discussion buttons and now I found the Remove button also didn't respond. All of these errors are demonstrable in this thread.
Regards,

I saw your test discussion and found the button below it unresponsive as are the appropriate buttons in this thread. I don't like to use Chrome because of my location. My browser is latest IE and I think your site should permit its use. It did until very recently lol:

I don't use any add-ons with my IE, at least none that I am aware of. I also have the same problem with iOS. If there is a difference in my behaviour as compared to before it is that I use the iPad to log in occasionally now.

What I'm saying is that I have the same problem on the iPad and the PC. I just never used the iPad for this site before and first encountered the unresponsive buttons on iOS. I attributed it to Safari but now I have the same problem on the PC. It's all the discussion buttons and the Remove (attachments) button. I can still attach workbooks and answer questions. I can also edit both questions and answers.
I use IE 11 on WIN 8.1

Edge is designed for Win 10 and using it on WIN 8.1 looks adventurous at best. I do appreciate your effort to enable my uninhibited access to TeachExcel but wonder if that point is so terribly important. At a guess, the large majority of your visitors still use IE and versions of Windows even older than 8. I think you have the good fortune that I'm telling you what's wrong and keeping me happy (quiet) will not solve the problem. I think the interesting question is whether, using Win 8.1 / IE 11, the same problem occurs in other jurisdictions. Have you been able to make that test at home? I intend to do so when I travel next.

I decided to kiss IE good bye since even MS doesn't support it anymore. It isn't that Chrome doesn't work. I just don't like all the gadgets and links that are second nature to Chrome being blocked. Anyway, I shall try to make Chrome my default from now on. Bad news for you though. Your buttons still don't work. In fact, that was to be expected since they don't work on iOS either. I think it's the Great Firewall targetting Java. For the past year or so (long before your trouble started) I've been getting the message "StackOverflow requires external JavaScript from another domain, which is blocked or failed to load.", also on both iOS and IE. If you kn ow which domain that is I might be able to assist with some research on it. However, I presume that Java is aware of it and would have done something about it long ago if it weren't political.
