This all works on the same forum software used by UDI but not here.
Here, there are no emoticons, pasting or quoting.
This has been a complaint for many users for at least a year, since I have been here.
These are the same restrictions for IE 10, IE 11, Edge, Win7, or Win 10.
However, tools do work from Raspian Midori browser.
It would seem when IE upgraded and added some features, just when the OS wars started, many sites decided to not support MS displaying stupid messages like, "You have an outdated browser. You can download Chrome, or we'll continuously try to force it on you forever"
I always just figured this was another throwback OS attack on MS products, so resided myself that the forum was never going to work. About a year ago the <> code tool started to work and pasting can be done in that tool, only. Other tools hang the browser requiring input and there is no way out of them without restarting the browser(s).
Well the rest was just deleted by hitting the backspace grrrrrrr... the wrong spot, again, so I am not going to retype those several paragraphs of experiment results.
Most of this has all been reported including who to discuss this with at UDI, after they fixed their same forum software, via the "contact us" at the bottom of the pages about a year ago.
