I use this app all the time and it works flawlessly. In fact, some of the new features are really welcome. For example, you can browse the contents of archives other than .sit or .hqx with contextual menu support. When I send a .zip to a PC co-worker, I can quickly find out if those pesky .DS_store files are there-- and eradicate them. Kudos to a great job and excellent product. One of the best purchases I've ever made.
