All right, I must admit, this beta build looks a lot better than any 1.4x
builds so far. When I installed it, I didn't use imagecfg to restrict it to
one CPU core, and so far, it has not randomly crashed on me. It also seems to
be finally respecting the exclusions in the site options part of a mirror. It
also seems to have gotten rid of some of those error messages (like the binary
message, or the 00800 message). However, I do have a new error message that
wasn't in the previous builds:
No data (connection closed)" (-4) after 2 retries at link (example link is
content.yieldmanager.com/rmtag3.js).

So, a few steps forward for fixing some errors (WinHTTrack really went
downhill after the 1.3x builds), and one step back for introducing a new error
message...
