Max 10 active objects in dashboard?

Is there a hard-coded limit for how many (active/dynamically updated) objects you can have in a dashboard?

It seems that with 10 objects I can save the dashboard just fine, but when I add the 11th, nothing happens when I click the save button (tried in all different browsers).

Have looked in the code without finding any hardcoded limit, but maybe (probably) I missed something..
