[xmonad] Can not restart Xmonad

[kedals0 at gmail.com]

Hi,

I can not restart Xmonad without quiting X.
When I launch xmonad from console, I get the following error:

toto at compaq:~$ .xmonad/xmonad-x86_64-linux --help
X Error of failed request:  BadAccess (attempt to access private resource denied)
  Major opcode of failed request:  2 (X_ChangeWindowAttributes)
  Serial number of failed request:  7
  Current serial number in output stream:  8
toto at compaq:~$ <stdin>: hGetLine: end of file

I'm using a compiled xmonad version from darcs:
toto at compaq:~$ ghc-pkg list --user |grep xmonad
    xmonad-0.10.1
    xmonad-contrib-0.10.1

toto at compaq:~$ ps aux |grep xmonad
toto    17397  0.2  0.3  55652  5124 ?        Ss   10:03   0:05 /home/toto/.xmonad/xmonad-x86_64-linux


Any ideas ?

Thx in advance,
Dal
