One week ago, I had only ubuntu 12.04 on my machine, I was exited of the improved speed of the software-center. But yesterday, I erase ubuntu and after fresh install of windows 7, I install ubuntu 12.04 again for dual OS, because I need property working of Photoshop. So, what is my problem: Now I must wait about 4-5 minutes software-center to start, until this happen there is only a blank screen. I reinstall software-cente, without any effect.
Any advices?
