After installing updates this morning, I could not login to KDE any more ("startkde not found"). I reinstalled KDE and solved that problem.
However, something has changed, because now I have to double click on the taskbar to maximize/minimize open applications, which is really annoying!
Is there a way to go back to normal single click behaviour?
I have Googled and checked the system settings, but found nothing that I could logically relate to this problem.
