xubuntu software center would become unresponsive

hi when i am installing softwares using xubuntu software center in 13.04 , it becomes unresponsive.
i blieve in xubuntu 12.10 and 1204 it was n't like this , while installatin ois going i could still navigate and search other softwares and add them to installatino queue.

But now its not possible , once one all softwares in queue are installed only then it would become responsive you can search new software... painful. CPU usage of software center are 50%-90% all this while ...

all other applications are responsive at this time, its only software center who is unresponsive.

please make it multi threaded if its already not. reduce the priorityy of installation thread and keeop the main UI thread's priority high, where your can browse for other softwares.

I would suggest the best would be that you give an option to add software to basket/cart( isntallatino queue) and how his basket/cart i top right. give an option to start installation manually or when user exits software center, throw a dialog and ask user to install everything he selected.

Let user browse and select al lthe softwares that he want to install/uninstall in one go... and later he can execute his changes.
as we do in gparted, you do all your partition related operations and then either you say manually that apply all changes or when you exist gparted it would ask you , do you want to apply these changes.

please see the attached screenshot. software center is so unresponsive that its not even able to paint itself... sad
