Just experimenting with some different settings, or trying, and when I set internet zone security to high and click on reset, it appears that the change hasbeen made but when I go back in the setting has reverted to medium.
There is no 'slider' as far as I can see. I should have read the caption on the drop down field more carefully as this clearly says reset to custom settings.
Looks to me that I am not allows to change the custom setting to anything other than recommended by selection from the drop down list. Looks like the only way is to use the radio buttons to make amendments to specific protocols starting at the default for the zone.
