I finally got around to watching the last Webinar and proceeded to download Architect 3. I Renamed my old version because it was obvious that it was about to overwrite it (Im on a Mac). I fired it up and Created the Ticket Tracker Template application. I have made no modifications, all I have done is test drive in a browser and when I go to add a Default based them and then scroll down to select a theme, the window just goes to all white without me ever even getting to try to select a theme. I have tried this several times with the same results everytime. It does not show as unresponsive if I do to Force Quit Application splash screen but it never recovers. I was wondering if anyone else was seeing this problem or if there is something that Architect does not like about my version of Ruby or maybe SASS that I have installed on the Mac? I have never had any problems compiling with Sencha Cmd so I feel pretty good about Ruby and SASS. Any thoughts?
