Permission Denied for 'other' users

[farseer]

I have setup CVS under CYGWIN + XP.

When i commit files, they are added to the repository as read only
always (-r--r--r-- or -r-xr-xr-x).  this means when anyone else does an
update and tries to work with these files, he/she is unable to commit
changes.

does anyone know of the possible causes of this and how to correct?

thanks much
