I started a desktop calendar widget called "rainlendar2" from the command line with:

nohup /usrlocal/bin/rainlemdar2/rainlendar2 &

Now every time I boot up KWrite pops up up a doc called nohuo.out that says:

rainlendar2: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0.

#################

And the KDE Session Manager pops up with this:

Error launching /usr/share/applications/kde4/kwrite.desktop. Either KLauncher is not running anymore, or it failed to start the application

Any ideas on how to stop this?
