I'm about 80% through the System Architect Training 7.2 and for some reason the context menus on right click have stopped working and instead I receive the browser specific context menus i.e. Back, Reload, Save As etc. I have been successfully using Chrome as the browser of choice but when this started happening yesterday I switched to MS Edge with slightly better results but it was still flaky. Any suggestion about what might be causing this? I've tried the usual rebooting, restarting the training environment etc but with no noticeable change.
