When I go in View | Preferences RobotC 1.10 crash/disappear without trace!
Everything else works and fortunately I don't need to change anything in the preferences - I can see that because RobotC works without problem on another of my computers!?!
They are both Dell running Windows XP SP2. The one with the problems has a Bluetooth stack which the MindStorm installation program marked as incompatible. On the other computer where RobotC 1.10 works (a laptop) the Bluetooth was recognized but may or may not work - I haven't tested it yet.
