There is a good chance that it is the check_can_write_on_non_blank_dvd() that is getting in the way. I never have liked this subroutine, though I can reluctantly admit to the necessity, but it has never had "proper" code to ensure that it is only called at the right time. I have had this on my todo list for some time, and I suspect that after the code reorganization I did last time, this will not be too hard. If you are interested in trying to tweak this, I suspect that you can just add an additional test to the if that is around the check_can_write. It should not enter the code if we are going to append (mode != OPEN_READ_ONLY). ------------------------------------------------------------------------- Using Tomcat but need to do more?
