ES is turned on in the main menu, not via the info screen. If you have the correct FW installed, when you press the menu button the camera menu pages come up, use the rear scroll wheel or right arrow button on the 4 way controller to get to the second page, the first option at the top of the second page is 'LV Electronic Shutter'. This needs to be changed to 'ES On'. You then leave the menu.
Try entering LV once you've done this with the drive mode in single image release. That's all I'm doing and it works for me. I got stuck with how ES works at first thinking it's turned on using the info page. I couldn't work out how to do that but with ES turned on in the main menu it would be triggered automatically once I entered LV.
Also, there might be a difference in how our cameras are set up and you might have something on that disables ES. Have a look at the instruction add on that came with FW 1.40 (I think it was that one) for anything that disables ES.
