Single click on remote site

I'm looking for settings, where I change actions for single click on remote site.
I would like to select file on single click only.

Files are selected with a single click by default. So I don't know exactly what you mean.

When I click on the file, it open clicked file in associated progam.
I have set "single click to open" in Windows XP.

In SmartFTP settings I can set action for doubleclick, but not for single click.
It's same like a Windows settings.
In WinRAR I can change this settings - open file after single click or doubleclick.

Are you using Windows XP?
