Why is tkeclipse not responding?
If your program is running, tkeclipse may respond slowly during heavy computation. However, the “interrupt” button always works: you can then choose to continue or abort execution. A second reason tkeclipse may not respond is if you have the Tracer open. In that case, during execution, the Tracer has focus; the main tkeclipse window will not respond (apart from “interrupt”). Finally, if tkeclipse really has locked up, under Linux hold down Control and Shift and click “interrupt” to kill tkeclipse.
