Actually, according to Tim Charron, the Win32 checkpoint bug is fixed in
fracbuild 335 and greater.  I just now tested this with the Win32 CLI
version of 357 and can verify that in fact checkpoint files are now read
during client startup.  I presume the hidden client is fixed as well. 
I'm sure you know this already, but for the benefit of any newbies out

Just find the following line in the .INI file and change the "none" to a
filename you'd like to use as a checkpoint file (ckpoint.rc5 is


I believe you can set the client to write the checkpoint as often as
every minute:


That way, you would still lose some cracking cycles on a reboot, but not
more than a minute's worth.

You are correct.  I remember this bug being brought up many weeks ago,
but it does not seem to have been addressed. Maybe Tim will have time to
look at it once the v2.7 clients are out.
