Yes, thanks. Actually, I can't reproduce this behavior. I have tried
several different ways. Sorry ... I should have tried to reproduce it
first before I mentioned it here. I can't reproduce it, but I don't
think I did anything "wrong" either. I guess it will remain a mystery.

I found another not-so-nice thing today, but at least I understand it.
If I add a directory in my branch, then try to switch back to the trunk,
I get an error and a half-switched working copy. This is because when I
switch, it wants to delete the directory, and I have some compiler
output stuff in there. I needed to do a "make clean" before switching,
and make sure all extraneous files and directories were gone (we use
sub-directories to hold the compiler output). I realize now that this
is only a problem when adding/deleting directories. I wish it would
just "un-version" the new (version-controlled) directory instead of
leaving the working copy in a half-switched state. The error it gives
is "Won't delete locally modified directory '<full path>'". Like I
said, it's too bad this couldn't be a warning instead of an error, but
it's probably "safer" to make an error and stop. If nothing else, it
would've been "polite" to try to reconstruct the previous contents of
the working copy, but I suppose that's easier said than done.
