How to save Radio autoscan presets on a H140???

[MadMaster]

Installed yesterday's build on my iRiver140.

After switching on the radio for the first time it asks if there should be a autoscan.
After hitting the Navi-button it starts scanning en several stations are added as presets.
After hitting the Stop-button it asks 'Save presets?'
After hitting the Navi-button a screen shows up with a default filename that can be used to store the presetlist (the name is fine to me).

Which button do you have to use to save the presetlist?
I've searched the manuals, this forum, tried several buttons on the iRiver, but nothing seems to work.
I also tried to use the 'Save Preset List' option in the submenu of the FM Radio, but that doesn't seem to work either.

Anybody?

use play-pause button to save. I have a h100, but I guess it is the same button on a h140.

Nope, hitting the Play/Pause-button doesn't work, not even pressing it for a long time...

Already found the answer myself by hitting the buttons in all possible combinations...  

After the default filename shows up (or after you editted that name offcourse) you have to double-click the Play/Pause-button to save the Preset List.

As far as I know, nowhere else double-click is used...
