We are using in company last Corona 1.0 version (Corona_1.00.01) and all time we have this problem with listed menu (right click in 3d max). Picture in attachment.
Hi. Uninstall Corona (the uninstaller is available in the universal installer), then install it again. If this doesn’t help, try this:

AFAIK you will also have to go to customize → quad and either delete it manually, or reset the quad menu to defaults
