[Xy-pic] Problem with curved arrows to circular regions

[Stefan Fink]

Hi Bjarte,

I think this one is comparable to my problem I had a few weeks ago, see 
this thread:

http://www.tug.org/pipermail/xy-pic/2003-November/000231.html

I hope, we will see a new upload of xy-pic at ctan with integrated 
patches, soon. (@Ross: if any help is needed, let me know!)

Regards, Stefan.
