Bug 32553 [Viewers] Closing a project does not remove [+] icon
I just launched I20030220 and imported a couple of existing projects into the workspace, with the [+] icon by each project (denoting contents). I then closed a couple of the projects that I was not looking at, and the [+] icon remained after closing the projects. Of course clicking on this icon resulted in nothing happening, except the [+] disappeared. It would be better if the icon was cleared when the project was closed. Mac OS X.2.4 Eclipse I20030220

return;
		
		
		final Collection runnables = new ArrayList();
		processDelta(delta, runnables);
		if (runnables.isEmpty())
			return;
		
		if (ctrl.getDisplay().getThread() == Thread.currentThread()) {
			runUpdates(runnables);
		} else {
			ctrl.getDisplay().asyncExec(new Runnable(){
				/* (non-Javadoc)
				 * @see java.lang.Runnable#run()
				 */
				public void run() {
					
					Control ctrl = viewer.getControl();
					if (ctrl == null || ctrl.isDisposed())
						return;
					
					runUpdates(runnables);
				}
			});
		}
	}
