Sorry, I can not really remember the situation. The Workbench icons do not seem to be aligned, I guess after booting or rebooting. Maybe I just can not remember this very well. It may have been fixed since then. Maybe I am still asleep.
I did not now about the Right-Amiga double click. The way Aros can go back up with the Arrow is good for me.
I would like to get documentation on the Amiga OS.
Wikipedia, I believe,talked about the modularity of Amiga OS.
This could be why there was some cool add-ons for the Amiga.
