It looks like you're new here. If you want to get involved, click one of these buttons!
Wonder if this pertains to the "ruler doesn't work" thread, but I get a ruler by clicking the banner icon - just, there's nothing under the (looks like) ruler options pulldown, it does nothing.
The pulldown next to "Add" also gives nothing (seems like it should offer choices of shape types?). I can't tell whether these pulldowns ever had content under them, whether other people have content and my setup has a problem, or whether the pulldowns are just "window dressing".
