Hotbuttons resetting

[gm9]

I'm not sure what you mean with hotbuttons resetting to default, but in any case nothing should happen upon opening the options window.

Regarding the colors of class icons being mixed up - the icons are just a graphics file, one of the Default UI at that, and the colors cannot change unless someone changes the graphics, which I have not done.

So something really weird is going on for you, maybe start by doing a full file scan and by renaming your uisettings.ini file (those sometimes get corrupted) and see if that helps.
