im not sure if i understood, but, i did not removed a poiter of an already removed pointer, nor acessing a pointer of a removed pointer..

i create the 1st panel, then i fade it out,then remove it with ptr_remove (now here, could is the problem , because it will remove a fading panel, and wont wait for it)
Anyway later on main(), i use the wait_for function to check when the panel is removed...

then i create a new panel.. but that panel is somehow affected because the 1st one, that has nothing to do with the 2nd. thats what made me wonder
