Ok, I am fairly new to KDE/Kwin and I did something I didn't want to do... I've tried searching for an answer and could not find any, so I hope I'm not asking a question that has been answered many times before, if so, please forgive me.

I have installed Kwin (and some KDE stuff) on my Lununtu 13.04... I accidentally turned off the borders for one application's window, and now I cannot find a way to restore them... the only information i can find tells me to right-click on the border to set those settings but there is no border to click.

I've tried right and left and even middle clicking with all the keys I can think of using, alone and in combo (ctrl, alt, super, shift) and no single key, combo of keys, or combo of keys with buttons seems to get the menu to set the borders for the window.

I have also looked in every settings box under system settings and desktop and such and can find nothing to turn the borders back on for that app... can anyone help?

The info screen tells me I'm using KDE SC version 4.10.05.

Try opening System Settings > Window Behaviour > Window Rules. Make sure only "(Default) Disable focus stealing prevention for Xv" is present.

thanks!
