Bug 21831 Debug events wait for further UI events
Reported: 2002-07-23 16:05:21 | Status: verified fixed

Build I-20020723 VM: J2RE 1.3.1 IBM Windows 32 build cn131-20020403 (JIT enabled: jitc) - new Java project - new class: public class Hello { public static void main(String[] args) { System.out.println("Hi"); System.out.println("Hi"); System.out.println("Hi"); System.out.println("Hi"); System.out.println("Hi"); System.out.println("Hi"); } - set breakpoint on first line - launch under debugger - wait until debugger settles down at breakpoint - hit F6 - nothing happens - wiggle mouse - the step occurs You may need to wiggle the mouse even to get to the breakpoint (seems to affect all debug events, not just step). At first I thought the debugger was just being horrendously slow, but if you wiggle the mouse immediately after stepping, or while clicking on the step button, it gets processed quickly.
