Z ignores new todolist.xml

I pulled /home/root/Applications/todolist/todolist.xml off of my SL 5500
onto a PC, created a new version, and put it back there, and the Zaurus is
ignoring it, as if the original was still there. There are no error messages
or anything else to indicate that something has changed. I even did a
Shutdown to see if the reboot would cause it to re-read the file that was
there. (It probably just overwrote what I had put there.)

Because the Task elements in the original todolist.xml all had Uid
attributes of 0, I set them to 0 in my version, and I set all rid and rinfo
attributes to 1. (I also set RIDMax to 1.)

Any suggestions on how to get it to read a new version of an XML data file?

thanks,

Bob
