How to set radar options, no OK button : LOTROExtreme

I am trying to set the radar options but so far have run into two problems:

1) Cannot find an OK button after making settings. and I also cannot close the settings window by clicking the X. I end up having to right click and close the program.

2) Trying to change color of "unknown" doesnt work. I click the color box, but nothing shows up.

nobody else has this problem?? Everyone can set the settings or see an OK button?

There's an OK button for the radar? I've only really used the vanguard radar, but that one didnt have an ok button since it was all instant.
But what settings do you mean?

Well i press the "T" button (i think) to change settings like radius, color, show npcs, show players etc.... but cant close that window to save changes. Or is it something else I have to do after choosing my settings?

same problem here. cannot close options window.
