This is probably an issue with the library code. Try contacting the vendor to see if they can fix it or alternatively switch to another component. If you don't need a managed solution and want faster compression you can try a native solution like Bricolsoft Zip ActiveX. http://www.bricolsoft.com/zip-activex-component.html.

This must be an issue with the zip library itself. try using sharpZiplib, i've used it a couple of times and works like a charm. http://www.icsharpcode.net/OpenSource/SharpZipLib/Download.aspx
