I just noticed this issue, because I haven't so far used the web interface, just tried that it worked. I tried to search for this issue but couldn't find it. Are other people able to control the SDS1104X-E using the web interface, Instrument Control menu? I'm not able to.
In my web browser, I can only see the oscilloscope window and moving signals, but there are no buttons at all, so I can't control the scope using the browser, only view the signals. In some manuals I can see that there is supposed to be multiple rows of buttons, just like on the real scope.
I've tried with Firefox and Chromium, but it looks the same. Below is a screenshot how it looks. Is this a browser issue, or what?
