Just tried that. Sadly didn't work, the screen is still greyed out, with that pop-up box trying to load. This time it did let me log in before locking up, though, and I thought for a moment the problem had been fixed! I'm at a loss to try and understand exactly what's going wrong, but suspect it must be that Trustarc thing trying to do something that the browser can't cope with. In my case, the browser that's giving the problem is Firefox 79.0, so it's up to date.
