Bug 82839 [misc] Breakpoint icons disappear
I am using 3.1M4 1 - Open a file and set a breakpoint. The breakpoint icon appears in the left and right margins. 2 - Close the file. 3 - Open the same file. Note the breakpoint icons no longer appear. The breakpoint is still there but the icons don't appear and you can't select them. This is a major problem because I can't see the breakpoints I've previously set so I have to clear those breakpoints and set new ones each time I run a debug session.

						removeMarkerAnnotation(marker);
						fChangesApplied= true;
						break;
					case IResourceDelta.CHANGED:
						modifyMarkerAnnotation(marker);
						fChangesApplied= true;
						break;
				}
			}
		}
