I found a really small bug in the latest mAirList version.
I have made the mix-editor as a fixed part of my GUI (via configuration - GUI - Screen Objects - Mix Editor) . When starting mAirList, without any tracks loaded to the mix-editor, clicking the Play, Undo or Redo buttons gives an error "Access violation at address XXXXXXXX in module ‘mAirList.exe’. Read of address 00000000.
I think those buttons shouldn’t even be clickable with an empty mix-editor.
