Bug 30007 Can't hit next in new java project wizard [build path] [code manipulation]
Build: I20020122 1) Open the new java project wizard 2) Enter a name, hit next 3) Hit the back button 4) Deselect the "Use default" check box 5) Type in a location -> It won't let me hit next, because it claims the project already exists. 6) Click cancel -> The project doesn't exist.
