I have no idea what happened but I am unable to select menu items. An example of this is under "All Plug-ins". The very first item "360 Stabilization" is highlighted, but I cannot select anything else in the list. I can open the "Render As" dialog, but nothing in the dialog is selectable. But when I open "Preferences" this does work OK but uses the more traditional menu. This was all working OK a month ago.

I've tried uninstalling / reinstalling all Vegas "items". After the uninstall I tried using a Registry Cleaner to see if that was it.

Nothing I've tried seems to work. I did install on an older machine running Windows 11 and that worked correctly. But that machine doesn't have the horse power I need. I tried searching the registry by hand to see if I could spot something. I was surprised that many items still have the "Sony" tag on them. But I could see nothing that sprang out at me.

This is only happening in Vegas 19, all other applications I run work correctly.

Windows 11 (up to date) / GeForce RTX 3070 / 64 G memory / Vegas Video 19 Pro
