Changed some of the adaptLayout calls in object selector. This should fix the bug where the objectselector shrinks when a new object is selected. If previewmode is enabled or there are other heavy widgets attached to the root widget, there will probably be a brief lag while the widgets get updated.

<Panel title="Select an option">
	<VBox>
		<ScrollArea min_size="150,300">
			<ListBox name="optionDrop"/>	
		</ScrollArea>
		<HBox>
			<Button name="okButton" text="OK"/>
			<Button name="cancelButton" text="Cancel"/>
		</HBox>
	</VBox>
</Panel>
