Click Only - Loot, Resurection

[Dawrid]

Hello all,
How hard would it be to make all the windows that have yes/no, accept/decline etc..., work with mouse click only? My main reason for asking this is, too many times have I accidently made a "choice", while trying to open a chat dialogue.

Anywho, hopefully this would be possible with a simple edit of a line of code within a particular windows XML file.

Thanks.
