I have a web panel for the grob g115 (tutor) that I have made interactive by overlaying clickable buttons over parts of the panel.
This was working perfectly in 2016.3.1, but doesn't seem to respond correctly to button presses in 2016.4.3.
For example, clicking on the main battery switch will change the expected property in flightgear, but the switch will not refresh to the thrown position until the page is manually reloaded.
I'm noticing similar refresh problems with the radio stack buttons in phi - one click swaps the frequencies, but a second click doesn't refresh and subsequent clicks are ignored until a manual reload of the page, so I don't think its necessarily a problem with my code.
I realise this might not be the most used functionality in flightgear, but I use it to provide a separate control panel on a touchscreen monitor, so was hoping someone might have some ideas?
