Choosing a focus point with an old lens - K20D

Hi all, I've recently bought a 50mm f1.7 M prime, and I've noticed that when I have it on the camera, I can't choose a focus point -- it's just stuck on center. I am 100% positive the mode wheel is on SEL, and if I put on any of my DA lenses (18-55 for example) I am immediately able to move the focus point. With the old prime, I can't. I have read that it might just require shifting the mode wheel around a bit to make sure it's locked on SEL, but no matter how much I move it around, I can't seem to be able to pick where I want to focus. I know this might be somewhat pointless as I can focus on my object at center and compose from there, but when moving the lens around, the distance to the object becomes slightly shorter (or longer?) when it's not on-axis with the center, and this can cause a bit of a focus issue when shooting wide open.

Has anyone else experienced this? Or is my camera just weird...

Currently Pentax DSLRs only support SEL mode with auto-aperture (A-series or higher) lenses, unfortunately. Dunno why that would be, but that's how it is.

Just lock your target with the centre point, and re-compose. Easy.

I would assume you mean using catch in focus. If you know how to put your camera in Debug Mode, in there you'll be able to select a different focus point by using AF area 2 or 3 (in the debug mode) then using the D-pad to select the focus point you want to use. Also useful if you only want to use focus confirmation.
