checkout problem with branch

[sjaditz]

Hi,
I tried to add a file to a branch.  It seems to work, the sticky tag is
set correctly, but when I try to checkout the branch later this file is
not included in the checkout (CVS 1.11.1p1).  In summary:

cvs add myfile
cvs commit -r mybranch myfile
cvs status myfile (indicates correct sticky tag)
cd;
cvs co -r mybranch -d dummy myproj (fails to checkout my added file)
BUT in the correct directory I can do:
cvs update -r mybranch myfile (retrieves my file properly)

What am I doing wrong?  Thanks,
Steve
