Blame my hosting provider, They've added some sort of filter recently and 
the false positive rate is unreasonably high.  I try to remove them from 
the subject line before posting.  Obviously I missed one.  Sigh.

Gee, I found it one of the more convenient ones.  You should try the ST10 
loader sometime :)  I prefer a command line based utility myself, and since 
one exists I'm quite happy.  As for those that download Intel Hex files, 
they've given me more grief than the Philips loader ever has.  As far as 
using 8K, none of that block is available to me anyway so whether it's 8 
bytes or 8K I can't tell the difference so why should I care?

Details?  I haven't run into this sort of behaviour so I'm kind of curious 
as to what you've seen.

I don't like this sort of behaviour myself, but strokes for folks.
