Well it turned out to be quite a funny story. I had thought that I made the
maksed cursor changes for 2.2, but of course there wasn't much usage of the
new version of Cursor. After some very puzzling debugging runs, I
discovered that Acorn won't allow cursor offsets outside the cursor extent
- and that no error is reported! Combine this with an ancient bug where I
was not inverting the Y offset and we get some very strange behaviour.
Since almost no cursors have anything other than a 0 at 0 offset, I hadn't
noticed the  problem before.
Now the only cursor with a problem is #corner, which wants to use -16 at -16;
so I have to put up with truncating to -15. Good enough for now....

2.3 for Acorn is now in the  usual places - ie my website.
NewCompiledMethod format work is being brought up to date ASAP.
