function key over ride

Hi guys,

Managed to customise the function key operation in keyboard shortcuts/over ride keys, so that I have several Fn keys set to Esnap override:xxxxx operations.

All dual designations were deleted and the box has been ticked apple's system preferences, to ensure that pressing a Fn key doesn't perform one of their operations.

However, when I use the Fn keys while drafting I find that they are variously, opening the command window and toggling Esnap etc. anything but what I set them up for.

as mentioned earlier, all other operations assigned to these keys had the key deleted in the "key" column of the over ride table, so how do I disable these seemingly default functions....

Stu.
