The windows will be maximum automatically when started

Hi,
I am a new Mageia user and using Mageia3 with the desktop environment of KDE 4.10. I face a boring problem now. Whichever program I started, it will be maximum automatically. Is there some setting to do with this ?
Some guys said that maybe the graphical driver is unhappy. Is that any way to re-install the driver? The graphical driver was installed automatically with the Mageia 3 system.
Thanks & Regards
