Quake 4 bugs?

I thought I'd see if anyone here has any clue on this; it keeps getting bumped down the queue with no responses on other forums. Also, UT3 will be my next game reinstall.

I have the latest patch (1.4.2) and have created an AutoExec.cfg as well as the original CFG file and still have these problems:

1. In Settings/Game Options/Gun Position >> it keeps defaulting back to Right and I want it Centered no matter how many times I change it. Is this command in the cfg file?

2. In System/Screen Size (on Ultra Quality Settings, aspect ratio 16:10) it keeps defaulting to 1440x900 and I want 1920x1200 as this is the native resolution of my LCD monitor.
EDIT: It's possible that it only shows this in the menu, but it is actually running at 1920x1200 (someone said this on the web somewhere and said he verified it; stupid fucking game bugs).

3. r_mode is set to "-1", but this sometimes is set back to "25" for some odd reason. Is it OK to make the Quake4Config.cfg file "read-only" because I'm not even sure it's reading the AutoExec.cfg like it should. I don't even know what a setting of 25 is supposed to do.

WTF gives with this? I tried making the config files "read-only" and that didn't as the game just changes it within the menu anyway.
EDIT: most likely another menu game bug.

4. Is it true that you can't make Quake4 config file read-only to be read-only and that they actually write to them anyway?
EDIT: Well, I just made my Quake4Config.cfg read-only and as many times as I go in and change the settings it does not change. AutoExec.cfg is not set to read-only and it doesn't change either like it should. Maybe the 1.4.2 patch eliminated the need for the AutoExec.cfg file.

Also, I've already checked with google searches and Quake forums, etc. with no luck. Maybe if I was asking 2-3 years ago, I'd get more of a response. Any ideas?
