The Agency: Some USB devices may cause hang on startup

The StarLogo Team posted a new FAQ item yesterday:

StarLogo starts loading and then stops. Why won't it load?

The problem may have to do with USB devices connected to your computer. The libraries that search for USB game pads and joysticks may be hanging when it finds other devices. Try disconnecting additional USB devices and send us a bug report (bug-starlogo@education.mit.edu) to let us know about the problem device.

So far we have received reports about this problem for a Sun mouse, a Sun keyboard, or an IBM mouse connected to a Mac Mini, as well as for the remote control connected to a Windows Media Edition PC.

This bug affects StarLogo TNG Preview 2 for some configurations of Mac OS and Windows.

Update: This problem was fixed in the Mac distribution on May 7. If you downloaded before then and are experiencing this problem, please update.
