4203 onscreen keyboard not working?

I was trying to run a plug-in test this morning, using the onscreen keyboard, and I can’t get it to trigger anything. I see no MIDI activity lights. Nothing showing in the monitor either. I’ve checked the MIDI Ports settings, which seem fine.

Anyone else seeing this, or is it another ‘just me’ moment?

Just me, then. Odd. I seem to be hitting a few ‘just me’ problems of late. I need to check my system…
