I am suspecting this has to do with the more recent fix in screen "covering" menus and such being closed when you are attacked to prevent you form dieing when you cannot see your character, in any event.
When opening the Report Abuse interface, if you are in an area with aggressive NPC's, or a random event pops up and attacks you, it will close the interface, this is an issue when attempting to report users, so what about keeping the interface open till you close it ?
It only takes a second or two to type in a RSN and hit the appropriate rule which has been violated, so I think the Report Abuse interface should be excluded from the normal interface closing feature.
Input on this?
More advanced suggestions for this?
Dumber suggestions for this?
Come with it, all input is good input you know :)
