["Darren Nickerson" <darren.nickerson@xxxxxxxx>]

Thanks for testing RC1 Kris, and for the detailed problem report! I've
opened a bug at:

http://bugs.hylafax.org/bugzilla

and I encourage you to file issues there yourself in the future, to make
sure they get prompt attention.

Subject: [hylafax-users] Problem with multistrip MMR encoded images


> When sending certain MMR encoded images the receiving fax machine does
> not print the page.  Also, the image sends much too fast for how large
> the tiff image is.  doc369_multistrip.tif is 123,866 bytes yet according
> to hylafax it sends the page in only 4 seconds.

> This problem only happens when HylaFAX does not need to convert the tiff
