Dear Kamel, As a rule, if you use binaries distributed by CCP4, you should ask them, not me.
However...
I am not able any more to scroll maps opened from .phs files with the middle mouse button (although I can change it in the map settings). I got the message: 'WARNING: No map - Can't change contour level.'
I can't tell from the information provided what the problem is. When reading a .phs file you should see a dialog asking which cell and symmetry from a previously read molecule you want to use for the cell and symmetry of the phs file. Is that what you see?
Feel free to send me a pdb file and phs file, off list, in confidence, if you think that I might be able to reproduce your problem.
Regards, Paul
