Toolbar visible, but non responsive

I apologize in advance for what is likely obvious.
The toolbar at the bottom is there, but nothing works. It doesn’t appear to be greyed out, but acts like it is.
The upper right dropdown dialog box allows me to build/run/clean. CTRL+ALT +B works, as does +U for load.
I know I must have fat fingered something somewhere, but can’t find what.
Thanks in advance.

Do only the PlatformIO buttons not work or all of them? Do you get the mouse hover effect on them?

Nothing works. No mouse hover. Interestingly, the row/column display works.

Can you deactivate all extensions in your VSCode extensions sidebar except Microsoft C/C++ and PlatformIO?

Everything is disabled except PIO, C/C++ and C/C++ Extension pack.

It was a vscode configuration problem. I uninstalled vscode, pio, no joy. Then copilot bailed me out. Went to command palette, preferences, set debug:toolbar to “docked”. All seems to work. How i ever screwed it up to begin with remains a mystery. Better to have things work and not know why than have them not work and not know why.
Fat finger, sometime, somewhere.
