Well, I've been saying for weeks that it is. I've been using it since the day of it's final release...4.05-02, that is. Try it. If you don't like it, you can use the "Back" folder to go back to 4.03. Make a separate copy of that Back folder first, before patching. The only thing I have a problem with is the new Object Import window. It's not standard Windows, and you can't do alot of things in it which you can do in windows, including read folder properties, delete files, copy/paste..that sort of thing. And rcreating a new folder doesn't work so well either. Actually, the problems with that window are rather annoying...
