Bug 81768 [Import/Export] Import projects wizard layout improvements
3.1M4 I found two small layout problems with the Import Projects wizard. 1. The Import Projects wizard does not call initializeDialogUnits(), and hence the "Browse..." and select/deselect buttons are not of the appropriate size. 2. The selection buttons create a layout but leave the default margins, and hence do not align correctly with the Browse... button.
bundles/org.eclipse.ui.ide/src/org/eclipse/ui/internal/wizards/datatransfer/WizardProjectsImportPage.java
.getString("WizardProjectsImportPage.SelectDialogTitle")); 
		String dirName = locationPathField.getText().trim();
		if (dirName.length() == 0)
			dirName = previouslyBrowsedDirectory;
		if (dirName.length() == 0)
			dialog.setFilterPath(IDEWorkbenchPlugin.getPluginWorkspace()
					.getRoot().getLocation().toOSString());
		else {
			File path = new File(dirName);
			if (path.exists())
				dialog.setFilterPath(new Path(dirName).toOSString());
		}
		String selectedDirectory = dialog.open();
		if (selectedDirectory != null) {
			previouslyBrowsedDirectory = selectedDirectory;
			locationPathField.setText(previouslyBrowsedDirectory);
		}
	}
	/**
	 * Create the selected projects
	 * 
	 * @return boolean <code>true</code> if all project creations were
	 *         successful.
	 */
	public boolean createProjects() {
		Object[] selected = projectsList.getCheckedElements();
		for (int i = 0; i < selected.length; i++) {
			ProjectRecord record = (ProjectRecord) selected[i];
			if (!createExistingProject(record))
				return false;
