I just moved from 0.7.16 to 0.7.17.
The Pages Tree View page in the admin takes ages to appear and finally it displays nothing (regarding the tree). I no longen have access to my trees. I went back to 0.7.15 and the problem remains.
I have installed a couple of other plugins in between my first 0.7.16 installation and 0.7.17 but I am not sure if there is a comflict or something.
