Thanks Arthur
We have suffered a lot in past due to HSphere and there was no reason for me to ignore your recommendation of HSphere control panel. A control panel provider should keep on updating versions with time and one should not allow end-users to run same version for years. Don't forget that there are many big companies deployed by various marketing agencies just to find bugs in various softwares.
Parallels has done big mistake by purchasing some of the dead softwares and they will never manage to recover their investment no matter what they do. We pay for license of over 100 VZ's and over 1000 plesk licenses. I feel sad to see them misusing our money for such abrupt purchases of dead companies and softwares.
