Tried deleting the line, didn't work. Also tried deleting the file all together which also didn't work.

If you mean doing /fontsize in-game, I tried all of them with restarting my game. None of them worked. How can I 'reset the text' though? What do you mean by that?

Yeah I can look around with my mouse, shooting etc. It's just on menu's like the one I showed.

For about 6 months I've had problems with the mouse icon in SAMP. When ever I am on a menu which requires moving my cursor ( choosing a skin or a car etc. ) I can see my cursor but it just dosn't move...
