HTML Help Workshop on Windows 10?
<p>Has anyone successfully used MS HTML Help Workshop on Windows 10?</p>

<p>I have run into a problem when I try to compile a package which has not caused any trouble on Window 7 for several years.</p>

<p>On Windows 10, the processing apparently never terminates, although it uses only less than 1% CPU after the first 10-15 minutes. I have to kill the processing. A CHM file is produced, but it can't be opened. The file is twice the traditional size: 1,2GB instead of ~600MB.</p>
