I went over it with 150 and 220, and got it to a glassy-smooth

sander right.

The first time I did this, I found two small spots (after staining)
that showed corkscrew sanding marks. I sanded them out by hand and
restained over them, and they seemed OK.

This time, even though I was being extra-careful, I've got corkscrew
marks all over the place. There must be at least 6-8 of them. And
naturally you can't see them until you stain.

Am I doing something wrong here? Should I only use the random-orbit
sander for rough sanding, removing material, etc, and use a regular
sander for everything else? Except most of these marks probably came
from the 40/60 grit, didn't they??

This is why I gave up on the random orbital sanders - seemed like maybe
some spot got clogged and *that* made the marks? Wasn't sure and the marks
really stand out. I've noticed the same in some craft show work.
