Hello! I just installed ACAD 2008 in my pc and I would like to customise the appearance. I don't want to have the coordinate box appear everytime I click on the screen. Same thing with the selection box, I don't want to have colours or anything like it. Basically I want it to look as similar as the previous version of ACAD I worked with (2005).Can anyone help me?Thanks!

To get rid of the coordinate Box just click the DYN button or hit F12 to disable the Dynamic input.
To get rid of the colors in the selection boxes check this post
