Please remember to mark the FIRST posting in the topic (SOLVED), not the last one 
I've done this one for you.
You'd named the file "SkypeAutostart", insted of say "SkypeAutostart.desktop"
The file needs to be called
some_name_or_other.desktop
Though once you populate it correctly it will display in pcmanfm by the name in the
Name=
line.
.desktop files are odd in this respect, their ACTUAL name needs to end with .desktop .. but when you add a "Name=" line to them their name will APPEAR to change in the GUI file manager .. but not in the command line.
Well, you learn something new everyday. Again many thanks
