Using com_easydiscuss (I suspect this is an issue with all Stack Ideas components) and the .mc-toolbar drop-down at the top is covered up by the component.
Issue:

What I did to fix this is added a CSS override for com_easydiscuss with this code...
div.mc-wrapper > div#content-box {overflow:visible;}
I haven't experienced any issues with this override and the issue is fixed.
