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;

			addedObjects = new Object[addedChildren.length];

				addedObjects[i] = addedChildren[i].getResource();
