terrible time with procmail

I have used procmail for several months now and all of
a suddend wierd things are happening.

I am running a script from the command line that sorts
by Netscape Inbox to folders that I specify.  The mail in
the Inbox does not get sorted and when the Inbox gets
written back out after running procmail most of the "From -"
lines are replaces with ">From -" so that these lines that
are replaced are not recognized as mail message separators
when I launch Netscape mail.  I cannot figure out why this
is happening.

Any help would be appreciated.

Attached is the script that I am running.

thanks
