Attached you can see how my settings are (i can't find a way to insert the images here in the text).
The rest is as default.
I've unchecked all toggling but left and right edges. But when i click on the central button to make it hide then it would not appear again if i move mouse left or right edge (i've even tried different pixel edges).
If i want to see the CD again i must find the shortcut in my tray...
The thing is that sometimes i do not want to see the CD on desktop to enjoy my wallpaper
but, of course, if i need cd again i prefer the moving mouse rather than clicking Mbutton or finding shortcut in tray.
Don't worry too much, its not a big issue, i can survive (i would not watch my wallpaper all days every day), the rest seems to work fine... i haven't tried your version long enough bc i am still kinda confortable with cd alpha 8.2. I'll keep on trying yours.
thanks for your interest
