I fixed the issue in BowlerStudio when it tries to open and there is no internet, it used to crash and hang, now it loads normally, AND your workspace is loaded so you still have quick access to your local files. This is a long-standing usability bug in network-denied situations. Now the application loads quickly and it easily ignores all the network operations.

WooHoo!
