Known bugs in Architect 2.2.2 (build 991)
Latest build: 991
OS X users launching Architect from the Dock get a blank Architect window
Architect has a bootstrap that needs to be run (the app from Applications). When you right click an choose to 'Keep in Dock' it's actually pinning the end game application which won't work.
Windows users with UTF8 character(s) in the OS user name can't launch Architect. The workaround until we get this fixed is to change your OS user name.
