I use the command..
xpluginhelper.sendcommand("command:category:variable set:<category name>:coverart:C:\blahblah.png")
However, this just sets the coverart field to 'C' due to the extra ':' in the string which is ovbiously interpreted as a field separator. Does anyone know if I can use anything else in place of this such as xlobby program dir or something that does not include a ':'.
(I wanted to use skin:// but this obviously includes a ':' as well so would have the same problem!)
