Ok, what seems to be the problem is that the program is using 100% CPU (4 core
CPU, using 25% CPU which is equivalent to 100% on a single core). Uninstall
and reinstall doesn't fix. I might try an older version - just have to find
one that is multicore compatible or I'll get the old 'WinHTTrack closes
randomly without error' problem. If it doesn't happen with an older version,
there was something changed in WinHTTrack that has caused it. If it does
happen with the older version - well, I'm screwed.
