[Trisquel-users] How to switch windows in KDE

[stephen . biggs]

I just installed Trisquel 8.0 with KDE. I can't switch windows or close  
windows. There are no close/enlarge buttons in the corner of the windows.  
Common keyboard shortcuts like Alt+Tab Alt+F4 don't do anything.

Has anyone else experienced this? Anyone know how to fix this problem?
Thanks
