I tried it 3 times with adjustment (actually just going through 1-5, without
doing any adjustment of the monitor itself) and 3 times without adjustment,
and the behavior was consistent.

*Bang my head on the wall*
Damn, yet another attachment I forgot to add..

So here they are. I first jumped strait to 6) (direct_calib),
and canceled (using Ctrl-C, ups..) during the second 64 batch (sorry, no
time this morning).
The adj_calib files were done straight afterwards (using menu options 1-6
without adjusting the monitor itself). It failed, like yesterday.

The monitor was running about 20 minutes before the tests started, hope this
didn't influence the tests to much. But yesterday I had the same behaviour,
after several hours.

Hope this helps, and thanks a lot for your software!
