sorry for my poor english, but i am very interested in learing CEGUI and thanks for your guessing and understanding!
I use openGl for rendering , CEGUI version is 0.7.9. Maybe my saying made you misunderstand and I think it's not "ghosting" because one of mouse coursors is as the same as Window system mouse cursor, the other is like the WindowLook cursor because i use the window loonfeel of CEGUI.
i suspect it's because the way of rendering but i don't know how to fix it .
Can't see the image? How could i make the image visible for you, can you provide a available website for image uploading ?
Thank you again, don't ban me please!
