Prob with running Blackbox 0.61.1
 

(sorry if i post this in the wrong section, but i am a newbie and this is maybe also a newbie question so...)

I just reinstalled RH 7.1 KDE cause i had a prob running BlacBox 0.61.1 . Every time i tried to run it i got this massage:
BScreen::BScreen: an error occured while querying the X server.
another window manager already running on display :0.0.
Blackbox::Blackbox: no managable screens found, aborting.

But now i still have the same prob, but i didnt install any other window manager so i dont know whats going on. :confused:

Pls let me know if u know whats the prob or have tips or whatever that is usefull.

tnx i.a.
