There are times when Architect is running great, and then times when you start to type and Architect freezes - you get a Not Responding message, wait a minute or two, and then Architect responds, but then it happens all over again. It's like the server is too busy, or something is dropping out, or maybe Architect is doing something in the background.... It's about to drive me friggin crazy!!! What is going on? Is there anyway to run in offline mode?
What platform are you on? I have never seen Architect 2 do this - I am on Windows 64-bit. Is there some local app interfering with Architect on your machine perhaps? Sencha does not need a live connection to the Internet (unless your application makes calls there) so it is effectively offline. I can run an app based on a local store and do everything in Architect including preview while disconnected from the Internet. Maybe you should uninstall and re-install.
I'm on Windows XP... it may be that I have spyware or something going on that is slowing down my PC. Has anyone tried PCMatic or any of the other programs that claim to speed up your PC... just wondering if they work well?
