AOZ Studio Beta

In the below the loadiff finds the logo file fine and displays it, however when trying to do a directory of the "drive" (or the iff subfolder) with the dir command, or when trying to set the directory with dir$ Aoz reports back a drive not found error:

#manifest:"amiga"
#speed:"safe"
#fullScreen:true
#splashScreen:false

//dir "AMOSPro_Examples:"  // drive not found error
//dir$="AMOSPro_Examples:"// drive not found error

Load Iff "AMOSPro_Examples:iff/Logo.iff", 0  // obviously works fine
wait key
