1.I selected some plugins to be installed, and click install button. On the second pop up panel, I check "run in background", so there is a progress in the NetBeans tray.
2.I opened the Plugin manager again, the clickable items in the GUI(available) were disabled.
3.I cancelled the running installation task, the Plugin Manager does not refresh the GUI....
I think if the running intallation task is canceled, it should notify the plugin manager to refresh the GUI and let user can select plugins again.

This belongs to Plugin Manager not Update Center itself. Reassigning, Jirko please evaluate. Thanks!
