Bug 46462 [RCP] [Preferences] Workbench switches to double click on each startup
N20031111 I use an pre-RCP workspace. On each startup I have to switch to single mode again.
bundles/org.eclipse.ui.ide/src/org/eclipse/ui/internal/ide/dialogs/IDEWorkbenchPreferencePage.java
IDEWorkbenchPlugin.log("Error changing auto build workspace setting.", e.getStatus()); 
			}
		}
		IPreferenceStore store = getIDEPreferenceStore();
		
		store.setValue(IDEInternalPreferences.SAVE_ALL_BEFORE_BUILD, autoSaveAllButton.getSelection());
		
		store.setValue(IDEInternalPreferences.REFRESH_WORKSPACE_ON_STARTUP, refreshButton.getSelection());
		
		
		
		store.setValue(IDEInternalPreferences.SHOW_TASKS_ON_BUILD, showTasks.getSelection());
		
		
		long oldSaveInterval = description.getSnapshotInterval() / 60000;
		long newSaveInterval = new Long(saveInterval.getStringValue()).longValue();
		if (oldSaveInterval != newSaveInterval) {
			try {
				description.setSnapshotInterval(newSaveInterval * 60000);
				ResourcesPlugin.getWorkspace().setDescription(description);
				store.firePropertyChangeEvent(IDEInternalPreferences.SAVE_INTERVAL, new Integer((int)oldSaveInterval), new Integer((int)newSaveInterval));
			} catch (CoreException e) {
				IDEWorkbenchPlugin.log("Error changing save interval preference", e.getStatus()); 
			}
		}
		
		return super.performOk();
