What does your configuration file look like? For example:
E:\programme\winboard\postmodernist>type pm.ini
TTSIZE = 21
TBDIR = e:\programme\winboard\nalimov
MAKELOGFILE = YES
TTSIZE is funny. It is not in megabytes. It's some multiplier that doubles the size each time. TTSIZE of 21 means a total of about 76 MB on my machine.

Hi Axel,
Could you email me the logfile? I don't mean the winboard log file, although that would also be helpful. I mean the logfile that PM produces. This will be called postmodernist.1234 (1234 will be something different).
If you could email it to me on A dot Williams at totalise dot co dot uk or the address in the README file, I would be VERY VERY grateful. It might be very long, so zip it if it's more convenient.
Thanks
Andrew
