Het forum

Hi, I am running Kubuntu Intrepid, with the KDE GUI. I am having a problem when i have multiple plaything windows open and have them on different desktop some of them will disappear when i go from one desktop to another. If other information is needed let me know and i will get back to you, I am pretty new to Linux so some things i may need directions on how to do it. Thanks for reading this, and any future help i may get.
