Is there way turnoff double click?

How do you change so it takes only one click to view a email?

[zdestiny]

How will you select it then?

[aevangelista]

hover over = select
ctrl+click = select
Click = open

Or you could enable a "gmail" type interface.

The email subjects could be single click hyperlinks, and there would be check boxes next to the subjects to select them.
