Hi Robert,

Thanks, I have run the script, both on

=> Windows: '2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit
(Intel)]'
=> And on Ubuntu: '2.5.2 (r252:60911, Oct  5 2008, 19:24:49) \n[GCC 4.3.2]'

In both cases the problem appeared almost immediately. I've zipped the
produced log file, the script used, and the console output (files attached),
so you can see for your self.
Also, on linux the logfile is cluttered with a lot of bianry 0 values. This
is consistent with what I saw with my own script.

Regards,

Frans
