Deneba has released a Canvas 3.5.5 Updater. It fixes a cosmetic problem in Mac OS 8. That's all it does. However, Paul Cheng writes that he had trouble getting the updater to recognize his 3.5.4 file (it reported: "invalid file selected"). Some problems like this are solved by making sure the application is unchanged from its original name.
Update: Deneba has apparently posted a new 3.5.5 Updater that fixes this problem. (Thanks, Liangkung Lin.)
