thats what i thought about your cover situation. glad thats sorted.
i plugged in my logitech usb/bluetooth mouse just a moment ago and it worked.
no cursor appears on the display so you cant quite judge where you are but I was able to open the library select a book and open it and then even turn pages with a double left click. right click and scroll wheel seemed to have no effect.
i could not seem to select anything in the in-book menu like font size change etc but that could be simply because i couldnt find where i was clicking.
