I'm on a Mac OS X 10.5.8 machine.
I used to use Arduino happily -- though not very often. This weekend I wanted to try it again, and discovered that it no longer works. That was Arduino 0017, so I downloaded and installed Arduino 0018, but it still doesn't work. At launch, it bounces once, appears in the dock, and then does nothing more; no windows or menus appear.
I looked in the console, and found these errors:
3/6/10 10:22:50 PM JavaApplicationStub Apple AWT Startup Exception : *** -[NSCFArray insertObject:atIndex:]: attempt to insert nil 3/6/10 10:22:50 PM JavaApplicationStub Apple AWT Restarting Native Event Thread
...and that's it. There is the standard application menu, which (as always) contains a Quit command, but Arduino ignores it; I have to force-quit it.
Possibly relevant: "java -version" on my machine returns 1.6.0_17; this isn't standard for OS X machines. I had to enable that for some other app that wouldn't run right under 1.5. (Ye gods, this is what I hate about Java apps!)
Short of disabling Java 1.6 (breaking the other app I need to run), does anyone have an idea how to get Arduino to work on my machine?
