The ILS frequency and course are inserted via the FMC. Look at the NAV RADIO page on the FMC and look for the frequency and course entry that is listed under ILS-MIL(Left LSK4). In v4.4, this becomes active when you reach about 20 miles from the airport, sometimes less. In v4.6, the ILS frequency and course are placed in the ILS radio as soon the plan is activated (see attached image).

I have do not have any trouble if I enter an ILS frequency and course, then landing using the LAND THREE on what I entered, regardless of whether I have a plan in use or not.

I don't think that unusual line in the image, that shows a likely problem with the graphics card, will cause this strange problem you are having with the ILS.
