I agree that it probably isn't needed, but I'd like to make it re-entrant if I can figure out the details. Chris Vleghert thought he had made all the needed changes, but I didn't get involved then. I let him handle the project for about 2 years. After he passed away I got back into it on the request of his brother. He wanted me to put together the most recent work into a new release. But it turned out to be much harder than I thought! I'll still try to get it done but I really appreciate the help from other programmers. My time is very limited.

Does anyone actually use the re-entrant capability of the dll's. I very much doubt that ZipBuilder/ZipMaster would handle it. The only time I can think that it would be used is with multiple streams but I think it would slow down pretty much - zip/unzip is fairly cpu expensive. Just a thought - Russell Peters
