Hi:
Until now I was not able to install pcmanfm, I always got that LOAD ERROR.
Now I just downloaded pcmanfm using the app browser and - see now it downloaded the extension and dependencies without any error messages. After that I installed localy and made sure that the files are in /tce/optional/...
and heat pcmanfm is in .onboot.lst
Now I have a minmalistic system:pcmanfm,dillo.openssh,awk,mc,nano, tigervnc and x11vnc - wow
I can not wait for the next release
TIP: I am using a HDMI - to VGA convertor cable and do not know what screen resolution I have. I have to user the CTRL-M function a lot to make the window visible.
