if u want 2d to stay on the screen all the time it has to be updated in the main loop always for it be present each displayed frame.
maybe u try something like this and instead of coloring the buttons place text on the screen in front of a color then grabbing a part of that into a texture location and texturing the button with text or images.

rem What does it Do???:
rem it automatically assigns a 3d plain as a button
rem it will also setup a mouse hot spot according
rem to the 3d button variables at the top of the code
rem
rem using these functions
rem
rem Make3D_btn(objnum,3d_btn_siz,3d_btn_x,3d_btn_y)
rem Place3Dbtn(objnum,X,Y)
rem Check3D_btn_(x1,x2,y1,y2,ms)
rem Delete3D_btn(objnum)
rem
rem easy to adapt for multiple buttons
rem
rem *** The Rotation and colouring
rem *** are just to show its usage
rem
rem What doesn't it Do???
rem It wont change its hotspot size if u wish to change the button
rem size dynamically in your project.
