Calc: active cell not highlighted or bordered

Ah yes. I had managed to find that box via a different route, but it didn’t have any effect. This time it did. And the paint can cursor has gone away too.
Many thanks!

Glad it worked out. Note that that default style modifier box does not work in LibreOffice Writer (only works in calc)

Thanks. Writer also has a problem with an almost invisible text cursor, but I’ve managed to find a workaround for that.
